Because some fish can adapt to both fresh and salt water conditions, does not mean that all can. Go buy yourself some fish for a marine aquarium, put them in fresh water, and observe how long they live.

John Woodmorappe, a YEC, predicted a sudden extinction of fish caused by the Flood. He wrote, "[P]resent-day marine life is but an impoverished remnant of that which had originally been created and had existed before the Flood" (1996, 142). However, the actual pattern of extinction we see shows evidence to the contrary. Living genera (plural of genus)become decreasingly represented in fossils as one goes deeper in the geological column, until there are no recent genera in the Triassic, and only about 12 percent of recent genera have any fossil record. Extinct genera continue back to the Cambrian (Morton 1998a). This pattern exactly matches what one would expect from evolution. It contradicts a global flood, which should include modern fish more or less uniformly throughout the flood-deposited sediments.

Plenty of dinosaur bones have been found at the very surface of the earth. They got there by erosion. The rock they are found in dates consistently with the rest of the worldwide geologic column. It isn't that the bones were always at the surface, it's that the rock originally above them has disappeared. I haven't seen anyone here who can explain this yet by any other idea than that radioisotope dating is erroneous (no proof here yet) or that scientists are liars.

I'm not sure what point you are making about shells in the sea, and sea creatures. You are aware of fossils, yes? Would you like me to link you to some sites that explain how they are formed, what the circumstances and processes are?

What does the fact that ice floats have to do with ice cores? Presumably you understand that ice cores are drilled from compacted layers of snow on land and not icebergs? If you have a 40,000 year old ice core from Greenland, and there was a global flood, you would expect to see sediment from it there. It isn't.

You also understand that there are parasites that are lethal to humans and animals, and that these would have had to have been present? You are telling me that the creatures on the ark, including only 8 humans, had to serve as living hosts for viruses, bacteria, fungi, and other microorganisms capable of producing pathologically based ailments -- and every single creature carrying them lived?

If the answers are as plain as day, then give them to me. I keep asking questions here because no one has answered them. If you are going to advocate a YEC model then it needs to be able to explain all the available data, including the questions I have posted here, and those are a very small sampling of what I could be asking. If a lot of 12 year olds know the answers to them then presumably you do too.
