There is an ancient Sumerian flood story that shares many elements of the story with Noahs flood. Here is the kicker, this story, the Epic of Gilgamesh is dated many hundred years before the Genesis account. (1)

Giza pyramids were built over two hundred years before the biblical flood purportedly happened

According to a biblical chronology by AiG, the largest and most prominent biblical creationist ministry, the global flood happened in 2348 BC. (1)

Yet, according to historians and archaeologists, Egypt has an unbroken historical lineage from two thousand years before this date of the flood. The evidence of this includes everything from excavated buildings to pottery and paintings to written records. (2)

In fact, archaeologists say the Giza pyramids were built between 2589 and 2504 BC, or two hundred years before the date of the purported global flood. (3)
