True, we don't know how we were created, but believing that someone/something just poofed us into existence even though there is proof that the earth is older than the bible teaches is just plain crazy. There is clear proof that we evolved. Where is your clear proof that God created the world?
If a God existed, which God would he be? There are many "God's" out there. "God" as a figure is just a way for humans to cope with that with which we cannot explain. All races, nationalities have some version of a "God" that they can blame/praise whenever something is unexplainable.
