The weird thing is that they really don't have to speculate about stuff like whether or not people who died in the flood would be resurrected. What difference does it make to admit there is no clear explanation, and that the matter is in god's hands? But, no! They have to offer explanations for things they can't know, which they will likely have to revisit and possibly disavow later.
It's like they recognize how much power they have over the following, and they feel that it will go to waste if they don't use it, so they use it frivolously just for the thrill. The possible long-term consequences don't matter to them, because they are certain there is no long-term to worry about.
