Sorry, but there is no such evidence. In fact the evidence proves the biblical account false. And common sense proves the notion of Noah collecting all species to be ridiculous. Really, Noah collected all the species of birds in the Amazon?<quoted text>
There is evidence to support a great flood. Whether you wish you to accept it or not is entire up to you. The evidence shows that you are incorrect.
A forty day rain induced flood submerged all the earth? Ever hear of the Water cycle? Where did the Divine water hose get all that water, and where did it go? Divine wet vac?
Ain't possible. Get real! Grow up!
Sorry, but some places underwater long ago in the same geological strata (which cover thousands of years) is not evidence of a worldwide flood that occurred in all of those places simultaneously over a period in which Noah could have sailed his supercalifragilistic yacht. And it certainly is not evidence of a worldwide flood that wiped out humanity and all land mammals, except for Noah and his family and his animals on the ark. Indeed there is no evidence for any such nonsense. If that were true, all of the species collected on Noah's nuclear powered warp speed yacht would show genetic diversity with a recent population bottleneck of two. That is simply not the case and your fantasy goes to the trash pile.
Three areas? Three areas ain't a worldwide immersion of the land mass of the world and die-off of nearly all land species in the past 10,000 years or so. The evidence shows that your fantasy is FOS.
