yup, there were many, many water catasrophes over millions and millions of years in many, many places.
why should all the dates coincide?
There's only one scientific model that predicts evidence of huge water catastophes on a scale far larger than any we've experienced in recorded history. And it's not evolution, it's not even intelligent design, it's creation.
Creation says there was one global flood. Now that we are repeatedly finding evidence of these phenomenally huge water catastrophes, shouldn't we be looking a little closer at the timing?
They don't. Next?
