Whether or not a civilisation is advanced is impossible to determine accurately without a record of the civilisation

Unless of course you find physical evidence of a sophisticated culture such as metal tools or megalithic ruins.

Your question was not whether it is possible for advanced civilisations to have been lost to history, but whether advanced civilisations have actually been lost to history

You're an idiot.

and that of course is impossible to answer because your own question precludes the answer.

No it doesn't you anti intellectual troglodyte cretin, it's a very simple question, were there advanced civilizations before the current historical records indicate? Just because something doesn't fit into the current consensus doesn't mean it doesn't exist. Just because we don't have the record for something doesn't mean it didn't exist and just because something wasn't recorded doesn't mean it didn't happen and there are other forms of evidence for civilization other than scrolls and tablets etc. you nincompoop, how can you be so stupid that you don't understand that you can estimate how advanced a culture was and when it existed from evidence such as the type of buildings they produced, tools and other artifacts, the type of weathering or oxidization or carbon dating on these artifacts and buildings etc. and connect the dots to figure out how old the fucking shit is and what kind of technology it would take to build it, there is plenty more to go on than written records you shameless imbecile. There are megaliths under water in the fucking ocean that have just recently been discovered around central america, japan and several other places. There is evidence of water erosion on the fucking Sphynx in Egypt which suggests it's much older than previously thought. They're still discovering pyramids and other structures in central america and africa and pretty much all over the world, there is even some ancient stone work in australia which was inhabited by primitive savages before english colonization according to mainstream history.

You can call me all the nasty names you like, pal.

Semen guzzling horse cock sucker egg mcmuffin butter balls bitch boy with a penis the size of a tardigrade and just as fucking ugly you insufferable foreskin moisturizing lotion-equipped masturbater spankin' it off to Bronto's crap filled diaper because you're a sick pedophile with a scat fetish you skunk breathed feckle wetted hymen lipped degenerate. You monkey fucking ass paddled hash addled fat ass hole, you abject colon stain, you resinous layer of fecal residue on the surface of a dung beetle's arse.

Your question is still stupid

Your thinking on the subject is so lazy and disengaged that you don't even notice how meaningless your objections are, the truth is you just don't care about subjects like this because all you care about is bashing conservatives and promoting your far left ideologies.
