I always laugh at the non-believer quoting scripture to bolster their argument. Satan tried the same thing in the wilderness, and it didn't work there either.Interesting. You're referencing scripture to bolster your argument that scripture is refrenced to bolster an argument.
As for the flood, I still haven't heard any reason why an all-powerful God who allegedly created the Universe needed to use rainfall to wipe out his disobedient children instead of just snapping his fingers and making them all disappear, save Noah. Couldn't this all have been done in an instant?
