Christian Apologists claim Noah's Flood really happened. Some have averred that the Flood account found in Mesopotamian myths is THE SAME HISTORICAL FLOOD appearing in the Bible but because details differ the Mesopotamian accounts are "corrupted" as the Bible is _always_ true.
In 1931 Archaeologists established that the Mesopotamian account was based on a "real historical event," but had been "embellished" as the physical flood silt evidence revealed it was a local flooding Euphrates river, not a worldwide flood covering mountain tops.
Sadly, the Christian world has _suppressed_ this archaeological information readily available in most Christian Seminaries and Colleges since 1931 not wanting the faithful to realize Noah's Flood is a myth.
