To be perfectly fair to Wumpini and ICANT, the opening post, which is what sets the thread and determines "on-topic" or off, was only stating that there is not enough water to flood the Earth to the extent mentioned in the Bible. All the other arguments about the impossibility of the flood, are therefore, off topic.
Wumpini then, in a great post, referenced a number of scientific journals that seem to confirm the fact that there is more water than Rhavin took into account. Again, the availability of the water was not mentioned in the OP. In fact, the OP specifically took unavailable water and used that as a strength of the argument.
I don't agree with Wumpini that there is evidence for the flood, but I do think he has quite admirably taken on the OP and argued that i is false. If you disagree with that argument, argue it on its own merits. If you want to start a Flood apologetics thread, feel free to do one. That was quite specifically NOT the point of this thread, as stated in the OP.
