zzzskizzzBecause flash floods happen all the time, and rocks don't get carved we can actually record the amount of rock that was weather down in a certain amount of time. And we know for a fact that it took millions of years for water to carve it out. We Also have a lot of writings books and libraries from ancient Egypt, not one of them refers to your claim. Only the Bible does that and because it's the only book that claims that to be true the actual people who were alive during that time didn't record it. that means........
Who has writings, books and libraries from that time? And where are they?
And sure flash floods happen all the time, but not of what that magnitude would've been.. And no you don't know for a fact that it took millions of years. If you knew for a fact you could give an exact number of years that it would've taken.
And I'm also quite sure that you haven't gone through every single ancient writing from that time to back up your claim
