My post with the sci-fi content wasn't intended to be taken seriously. It was satire.
If a centimeter of rainfall releases approximately 320,000 kJ of energy per square kilometer, then that same rain over the entire 510 million square kilometer surface of the Earth would release 163,200,000,000,000 kJ of energy. And that is just a single centimeter of rain. Is your answer that this energy does nothing? Keeping in mind that even with the fountains of the deep (whatever those are) it isn't likely that 40 days and nights of rain would be a single centimeter of rain, that is a lot of energy being released. How do you explain how that much energy leads to freezing of the Siberian mammals. Again, how did the flood sort them out so that only animals from that region would be right where you would expect to find their remains? How come there are no kangaroos in that mess? No armadillos, tapirs, whitetail deer, etc.?
What is the mechanism that would cause freezing of those animals that is so obvious, it should be easy to see, understand and explain while clearly it is none of those things?
