As far as I know there are YECs who will argue for a recent flood, OECs who will argue for a much older flood and there are Christians and non-Christians who don't believe a worldwide flood ever happened.This topic is about looking for evidence of the recent flood, as described by YECs. That being the case, I'm strugging to follow ICANT's arguments. Am I missing something very basic here?

I'd appreciate someone checking this out for me because me and numbers have "issues" with each other.Using the radius of the Earth I've calculated the volume, then using the radius plus 4000 metres I calculated it again (Everest is approx 8000 metres). The difference between the second figure and the first figure gave me the volume of water required to cover the Earth's surface completely.I'm not claiming accuracy here, more of a rough guesstimate, a ballpark number and it comes out at 2046 million cubic km. To help get an idea of what that means, the Earth's crust is estimated to be 1332 million cubic km (I googled that).Even if it's argued that the mountains weren't as high at the time of the supposed flood, you're still talking about alot of water.

So that's roughly the same, is it not? I have trouble with UK billions and USA billions, so I avoid them all like the plague.

Percy is correct. I used half the height of Everest to get a middling figure, given that some do argue that the mountains were not as high before the flood.
