You are comparing yourself, a sinner, to the omnipotent God of the Bible. Jesus believed the Genesis Flood account, but of course He was there.
Luke 17:26-30 (NKJV)
[sup]26 [/sup]And as it was in the days of Noah, so it will be also in the days of the Son of Man:
[sup]27 [/sup]They ate, they drank, they married wives, they were given in marriage, until the day that Noah entered the ark, and the flood came and destroyed them all.
[sup]28 [/sup]Likewise as it was also in the days of Lot: They ate, they drank, they bought, they sold, they planted, they built;
[sup]29 [/sup]but on the day that Lot went out of Sodom it rained fire and brimstone from heaven and destroyed them all.
[sup]30 [/sup]Even so will it be in the day when the Son of Man is revealed.
Oh yeah, Jesus also believed the burning of Sodom account. He was there too.
