Not retarded, certainly plausible that early earth had a different atmospheric composition that did not have the water cycle as we know it to be now. Certainly also plausible that water came from space in the form of ice and entering the atmosphere caused floods. Also plausible that there was in fact an array of ice orbiting a primordial earth and that water under the earth could rise up to irrigate land. Lots we don't know so chill.
What?
there wasn't even rain before the flood happened
Are you trying to fuck with me? I honestly can't tell with a lot of the retardation around religious types.
