If this is a serious question, I've always heard that it had never rained on the earth before the flood. Water always came up from the ground (dew, springs, etc).
When the flood happened, it not only rained, but God let the waters flood up out of the earth....
I've also heard that mankind did not eat animals until after the flood, but were vegetarians... I don't know if that is true, as I have not researched it... but it's an interesting concept.
Neither of those two tidbits make any difference toward your salvation, however, just like figuring out exactly what the Nephilim were... interesting to think about, and study, but not necessary for salvation.

There, your study on if mankind was only vegetarians before the flood is completed.
