There is definitely enough water on earth to cover it.
"Young Earth" creationists may have a pat answer for everything, but it isn't all that convincing.
One scientist estimated that for a 40-day rainstorm to raise sea levels high enough to cover Mt. Ararat, the rain would have to come down at about 15 feet an hour, which would be like being under a waterfall. Wonder how the Ark survived?
Also, where did Noah put the aquariums, and how did he maintain them? The flood water would have been saline, which would have killed all freshwater species, so there would have had to have been a lot of aquariums on the Ark.
your assumptions are all wrong,
since you’re not serious I’ll not waste the time.
