It's not physically possible for a planet to form from debris; grow to a size where gravitational energy causes its core to heat up; to undergo the collision processes that precede layering; to settle into a stable orbit (along with the other seven planets); cool on the surface; undergo abiogenesis; and for life to evolve and diverge as much as ours, in 10,000 years.

We literally have stone tablets with written human language that predate the time-frame you propose the Earth was created in.

It's ludicrous. Nobody with any scientific literacy could believe this.

This ancient zircon crystal is the oldest known material formed on Earth. Scientists have dated the crystal to about 4.4 billion years, making it the earliest confirmed piece of the planet's crust.

The world is billions of years old. Anything else you would like to know?

Distant starlight

When you look at an object a mile away, the light has been traveling for five microseconds. When you look at the Sun, you are seeing light that has been in transit for 8.3 minutes. When astronomers look at the closest star to Earth (Alpha Centauri), which is roughly four light years away, they are seeing the star as it was four years ago from our perspective. When astronomers look at objects in the region of space known as the "Hubble ultra deep field", they are seeing the stars there as they were over ten billion years ago. Light we are receiving from these fields has been traveling for ten billion years, and the universe must have, therefore, existed long enough for that transit time to take place.

Helioseismology

The composition of the Sun changes as it ages. The differing composition changes the way sound waves behave inside the Sun. Using helioseismic methods (models of pressure waves in the sun), the age of the Sun can be inferred. Using this method, an Italian team came up with an age of 4.57 +/- 0.11 billion years.

Lunar retreat

South African rocks studied by geologist Ken Eriksson contain ancient tidal deposits indicating that at some point in the past, the Moon orbited "25-percent closer to Earth than it does today." The distance between the Earth and the Moon is 384,403 kilometers, so for Ken Eriksson's work to fit with a YEC timescale the Earth would have to have been receding at a speed greater than 15 kilometers per year. However, the Moon is currently receding from the Earth at a rate of 3.8 centimeters per year.

Radioactive decay

Radioactive decay is the constant predictable decay of unstable atoms into more stable isotopes or elements. Measurements of atomic decay are generally considered one of the most accurate ways of measuring the age of an object, and these measurements form the basis for the scientifically accepted age of the Earth. There are many different variations of the radiometric dating technique such as radiocarbon, argon-argon, iodine-xenon, lanthanum-barium, lead-lead, lutetium-hafnium, neon-neon, potassium-argon, rhenium-osmium, rubidium-strontium, samarium-neodymium, uranium-lead, uranium-lead-helium, uranium-thorium, and uranium-uranium, of which every single one will date objects far older than 10,000 years.

Because radiometric dating is one of the most commonly used methods of determining age, these techniques are under constant attack from young earth supporters. A few creationists, armed with only a cursory knowledge and a desire to think that they're better than scientific "experts", may misunderstand radiometric dating and just not believe it works. This is often accompanied by ignoring the high concordance of radiometric methods.

Length of the prehistoric day

Work by John W. Wells of Cornell University, New York has shown that certain pieces of extremely old coral show evidence of a growth rate which reflects a time when a year had 400 days of 22 hours each. Because the rate of change of the rotation of the Earth is relatively predictable—about 0.005 seconds per year—one can calculate the last time a year had 400 days, which was about 370 million years ago (which is also about the same as radiometric dating of the coral).

Widmanstatten patterns

Widmanstätten patterns are crystals composed of nickel and iron that are found in some meteorites.

Nickel-iron crystals can only grow to several centimeters when they cool at an extremely slow rate of about 100-10,000 degrees Celsius per million years, from a starting point of about 500-700 degrees Celsius to a temperature of about -73 Celsius. Even at its shortest (starting at 500 degrees and cooling to -73 Celsius at 10,000 degrees per million years), this process would still take 57,300 years. The longest cooling ages have been reported at 10 million years.

Naica megacrystals

The Naica Mine of Chihuahua, Mexico is the home of some of the largest gypsum crystals on earth. Specimens in the area have been found to exceed 11 meters in length and 1 meter in width. Based on classical crystal growth theory, these crystals are older than one million years.

Nitrogen impurities in natural diamonds

Nitrogen is the most common impurity in natural diamonds, sometimes by as much as 1% by mass. Recently formed diamonds, however, have very little nitrogen content. A major way synthetic diamonds are distinguished from natural ones is on the basis of nitrogen permeation. It takes long periods and high pressures for the nitrogen atoms to be squeezed into the diamond lattice. Research on the kinetics of the nitrogen aggregation at the University of Reading have suggested that a certain type of diamond, Ia diamonds, spend 200-2000 million years in the upper mantle.

Petrified wood

The process in which wood is preserved by permineralization, commonly known as petrification, takes extensive amounts of time. Gerald E. Teachout from the South Dakota Department of Game has written that "the mineral replacement process is very slow, probably taking millions of years".

It is true that in the laboratory petrification can be achieved in a matter of months, but petrification is far slower in natural conditions.

Relativistic jets

A relativistic jet is a jet of plasma that is ejected from some quasars and galaxy centers that have powerful magnetic fields. It is conjectured that the jets are driven by the twisting of magnetic fields in an accretion disk (the plate-like cloud of matter) found encircling many celestial objects. In super-massive bodies, immensely strong magnetic fields force plasma from the accretion disk into a jet that shoots away perpendicular to the face of the disk. In some cases, these columns of plasma have been found to extend far enough to refute the idea of a young universe.

For example, the quasar PKS 1127-145 has a relativistic jet exceeding one million light years in length. Because the speed of light cannot be exceeded, this column must be over one million years old. Moreover, these jets are generally billions of light years from Earth, meaning they were at least a million years old several billion years ago due, again, to the speed of light.

Seabed plankton layering

Fossils of dead plankton that layer on the ocean floor is used to gauge temperatures from the past, based on the chemical changes of Crenarchaeota, a primitive phylum of microbe. Much like ice layering and dendrochronology, researchers drill through the ocean floor to extract samples which indicate annual temperature fluctuations in the plankton fossils, or "chemical rings" as it were. A 2004 pioneering expedition to the Arctic Ocean near the North Pole collected samples dating back to over 56 million years of temperature dating.

Sedimentary varves

Varves are laminated layers of sedimentary rock that are most commonly laid down in glacial lakes. In the summer, light colored coarse sediment is laid down, while in the winter, as the water freezes and calms, fine dark silt is laid down. This cycle produces alternating bands of dark and light which are clearly discernible and represent, as a pair, one full year. As is consistent with the old earth view, many millions of varves have been found in some places. The Green River formation in eastern Utah is home to an estimated twenty million years worth of sedimentary layers.

The creationist response is that, instead of once per year, these varves formed many hundreds of times per year. There is, however, much evidence against accelerated formation of varves.

Pollen in varves is much more concentrated in the upper part of the dark layer, which is thought to represent spring. This is what would be expected if varves formed only once per year because pollen is much more common at this time.

In Lake Suigetsu, Japan, there is a seasonal die-off of diatoms (calcareous algae) that will form layers in the bottom of the lake along with the sedimentary varves. If the 29 thousand varves in the lake formed more than once per year, there should be several sediment layers for every layer of deceased algae. However, for every one white layer of algae in Lake Suigetsu, there is only one varve.

The varve thickness in the Green River formation correlates with both the 11 year sunspot cycle and the 21 thousand year orbital cycle of the earth.

Amino acid racemization

[N]aturally occurring amino acid molecules usually possess a carbon centre with four different groups joining it; a hydrogen atom, the amino group, the acid group (hence the name of the class of molecule) and a side chain, which is what distinguishes amino acids. In three dimensional space, such a molecular topology can occupy one of two configurations. Convention labels these as D or L, which are referred to as stereoisomers and are essentially mirror images of each other. The ratio of these two isomers is initially unequal. With only one exception [glycine], naturally occurring amino acids used in polypeptide synthesis are in the L form. Over time this will decay to a more balanced state in a process called racemization, where the ratio between L and D stereoisomers will be equal (a racemic mixture).

Measuring the degree of racemization and other known quantities can show an estimated age of the sample. This is measured fairly unambiguously by the fact that different stereoisomers rotate plane polarised light in opposite directions (it is this interaction that determines the D and L labels) and so a ratio can be determined by contrasting an unknown sample with a pure D or L sample and a racemic mixture. By measuring the racemization of the amino acid isoleucine, for example, objects can be dated up to several million years old.

While it is true that there can be great variability on the rate at which amino acids undergo racemization, the changes in humidity, temperature, and acidity required to make the oldest known samples conform to a young earth (under 6000 years) view are completely unreasonable. Such conditions would destroy all traces of the amino acids rather than just leave a racemic mixture of the molecules behind.

Continental drift

Based on the continuity of fossil deposits and other geological formations between the South American and African tectonic plates, there is much evidence that at some point in history the two continents were part of the same landmass. Because tectonic drift is an incredibly slow process, the separation of the two landmasses would have taken millions of years. With modern technology, this can be accurately quantified. Satellite data has shown that the two continents are moving at a rate of roughly 2 cm per year (roughly the speed of fingernail growth), which means that for these diverging continents to have been together at some point in history, as all the evidence shows, the drift must have been going on for at least 200 million years.

Cosmogenic nuclide dating

The influx of cosmic rays onto the earth continually produces a stream of cosmogenic nuclides in the atmosphere that will fall to the ground. By measuring the build-up of these nuclides on terrestrial surfaces, the length of time for which the surface has been exposed can be inferred. This technique can be used to date objects over millions of years old.

Erosion

Many places on Earth show evidence of erosion taking place over very long time periods. The Grand Canyon, for instance, would have taken millions of years to form using the normal rate of erosion seen in water. Nevertheless, Young Earthers insist it was cut in a few years following the Great Flood - but in order for this to happen the rocks of the Kaibab Plateau would have needed to have the solubility of granulated sugar, rather than the more solid stone that it's made of.

In the case of the Yakima River in Washington State between Ellensburg and Yakima, the river meanders with many oxbows typical of a slow-moving river on a plain, yet it is set within a deep canyon with visible layers of erosion. The only possible explanation is that the pre-existing river maintained its original bed as slow tectonic forces caused the surrounding land to rise underneath and around it.

Geomagnetic reversals

A geomagnetic reversal is a change in the polarity of the Earth's magnetic field. The frequency at which these reversals occur varies greatly, but they usually happen once every 50,000 to 800,000 years, and generally take thousands of years. This fact is obviously inconsistent with the notion of a young Earth; around 171 reversals are geologically documented, which would make the Earth at least 8.5 million years old.

(If the earth was only 10,000 years old, that would mean a magnetic reversal would have occurred every 58.5 years on average.)

Iron-manganese nodule growth

Beryllium-10 (10Be) produced by cosmic rays shows that iron-manganese nodule growth is one of the slowest geological phenomena. It takes several million years to form one centimeter (and some are the size of potatoes). Cosmic ray produced 10Be is produced by the interactions of protons and neutrons with nitrogen and oxygen. It then reaches the earth via snow or rain. Since it is reactive, it gets absorbed by detritus material, within a timespan of about 300 years- very short compared to its half-life. Thusly, 10Be is excellent for use in dating marine sediment.

Coral

Corals are marine organisms that slowly deposit and grow upon the residues of their calcareous remains. These corals and residues gradually become structures known as coral reefs. This process of growth and deposition is extremely slow, and some of the larger reefs have been "growing" for hundreds of thousands of years. The Great Barrier Reef Marine Park Authority estimates that corals have been growing on the Great Barrier Reef for 25 million years, and that coral reef structures have existed on the Great Barrier Reef for at least 600,000 years.

Fission track dating

Fission track dating is a radiometric dating technique that can be used to determine the age of crystalline materials that contain uranium. As uranium decays, it sends out atomic fragments, which leave scars or "fission tracks" in crystalline structures. Because decaying uranium emits fragments at a constant rate, the number of fission tracks correlates to the age of the object. This method is generally held to be accurate, as it shows a high degree of concordance with other methods such as potassium-argon dating.

Ice layering

Ice layering is a phenomenon that is almost universally observed in ice sheets and glaciers where the average temperature does not rise above freezing.

Annual differences in temperature and irradiation cause ice to form differently from year to year, and this generates alternating layers of light and dark ice, much like tree rings. This method is considered a relatively accurate way to measure the age of an ice sheet, as only one layer will form per year. While there have been a few cases where several layers have formed per year, these incidents do not challenge the ability of ice layering to provide a minimum age, as these false layers can be discerned from the real thing upon close inspection.

Currently, the greatest number of layers found in a single ice sheet is over 700,000, which clearly contradicts the idea of an Earth less than 10,000 years old. Even if one were to assume an absurdly high average of ten layers per year, the age demonstrated by this method would still be far greater than that suggested by young Earth creationists.

Lack of DNA in fossils

Deoxyribonucleic acid (DNA), the universal carrier of genetic information, is present in all organisms while they are alive. When they die, their DNA begins to decay under the influence of hydrolysis and oxidation. The speed of this decay varies on a number of factors. Sometimes, the DNA will be gone within one century, and in other conditions, it will persist for as many as one million years. The average amount of time detectable DNA will persist though is somewhere in the middle; given physiological salt concentrations, neutral pH, and a temperature of 15 °C, it would take around 100,000 years for all the DNA in a sample to decay to undetectable levels.

Permafrost

The formation of permafrost (frozen ground) is a slow process. To be consistent with the young earth creationist model, which states that all sediment was deposited by the global flood, there would have to be absolutely no permafrost present at the end of the flood, because any permafrost that was present at the moment of creation would have been melted during the flood.

Because earth is a good insulator and permafrost forms downward from the surface, it would have taken much more than the few thousand years allotted by creation theory to produce some of the deepest permafrost. In the Prudhoe Bay oil fields of Alaska, the permafrost which extends over 600 meters into the ground is believed to have taken over 225,000 years to reach present depth.

Weathering rinds

Weathering rinds are layers of weathered material that develop on glacial rocks. The weathering is caused by the oxidation of magnesium and iron rich minerals, and the thickness of this layer correlates with the age of a sample. Certain weathering rinds on basalt and andesite rocks in the eastern United States are believed to have taken over 300,000 years to form.

Thermoluminescence dating

Thermoluminescence dating is a method for determining the age of objects containing crystalline minerals, such as ceramics or lava. These materials contain electrons that have been released from their atoms by ambient radiation, but have become trapped by imperfections in the mineral's structure. When one of these minerals is heated, the trapped electrons are discharged and produce light, and that light can be measured and compared with the level of surrounding radiation to establish the amount of time that has passed since the material was last heated (and its trapped electrons were last released).

Although this technique can date objects up to approximately 230,000 years ago, is only accurate on objects up to 10,000 years in age. This is, however, still over 4,000 years older than the creationist figure for the age of the earth.

Dendrochronology

Dendrochronology is a method of scientific dating which is based on annual tree growth patterns called tree rings. The rings are the result of changes in the tree's growth speed over the year (since trees grow faster in the summer and slower in the winter). The age of a tree can be found by counting the rings and is the only method on this list that can date events precisely to a single year.

Now, any date derived from one individual tree is not in itself contradictory to the recent creation doctrine, since even the longest lived types of tree do not live longer than 5,000 years or so. However, it is possible to extend the chronology back over many different trees. This is done by taking the matching up living tree rings with dead tree rings, which go on longer than the living rings. Because the thickness of tree rings varies with the climate, a sequence of thick ring, thin ring, thin ring, thick ring, thick ring, thick ring, thin ring, thick ring is strong evidence that the corresponding rings formed at the same time. By observing and analyzing the rings of many different trees from the same area, including fossil trees, the tree ring chronology has been pushed back in some areas as far as 11,000 years.

Human Y-chromosomal ancestry

The Y-chromosome, unlike most DNA, is inherited only from the father, which means that all DNA on the human Y chromosome comes from a single person. This does not mean that there was only one person alive at that time, but that a single man's Y-chromosomal DNA has out-competed the other strains and is now - not taking into account smaller and less drastic mutations - the only one left. Because the only factor affecting the makeup of the DNA on the chromosome is mutation, measuring mutation rates and extrapolating them backwards can tell you when this man lived. The most recent calculations put this common ancestor as having lived 340,000 years ago.

Oxidizable carbon ratio dating

Oxidizable carbon ratio dating is a method for determining the absolute age of charcoal samples with relative accuracy. This dating method works by measuring the ratio of oxidizable carbon to organic carbon. When the sample is freshly burned, there will be no oxidizable carbon because it has been removed by the combustion process. Over time this will change and the amount of organic carbon will decrease to be replaced by oxidizable carbon at a linear rate. By measuring the ratio of these two allotropes, one can determine ages of over 20,000 years ago with a standard error under 3%.

Rock varnish

Rock varnish is a coating that will form on exposed surface rocks. The varnish is formed as airborne dust accumulates on rock surfaces. This process is extremely slow; between 4 µm and 40 µm of material forms on the rock every thousand years, and instances of 40 µm of accumulation are very rare. Because the rate of accumulation is generally constant, measuring the depth of the varnish can provide dates for objects up to 250,000 years old.
