So what does that mean for Noah's Ark? We now know that that story was inspired, or rather copied, from the Epic of Gilgamesh hundreds or thousands of years earlier and had no connection with the Christian God at all. Is Noah's Ark no longer considered scripture then?
While the Epic of Gilgamesh was written around the 18th Century BC, the events of Noah and the Ark transpired much earlier. Gilgamesh was derivative of the true events of Genesis, but adapted to fit Sumerian society and culture. Gilgamesh doesn't just have a flood story, it has creation and temptation stories as well. "Written first" doesn't necessarily mean "more accurate."
Noah was a truth story, not inspired or copied. Who tell you these kind of things? We are here, thanks to his natural descendant. Many people see Noah as a myth or fable, or a sensacionalist story. But He was real.
