1. Makes you wonder doesn't it.
2. I think you answered your own question. The word CREDIBLE just has to much meaning there.
3. Well, I wouldn't ever assert the earth is defiently 4.5 billion years. I've even heard of many dates being rejected because of this preconceived notion. I believe the earth is older than what YEC claim, a lot older. But that's still a devoloping science.
4. Good? I dunno.
5. It's a conspiracy!!! Well, I'm sure it would be something like that. Evolution is also asserted as fact in most science. I wonder if that has something to do with it. Also, Have you taken an English course recently? It pretty much just sets someone up to reject the Bible.
6. LOL, no.
7. Join the solving the Biblical flood thread. That's way to indepth here. Anyway, why would it be uniform? Did the water cover earth identically everywhere following the exact same patterns.
8. Nice point.
9. Dunno
Yes, this is going way to broad. Do you expect to argue all 9 points in one topic. There's topics already you could join I'm sure covering such issues. Attacking them with a heap of questions is a real straw man approach. What are you trying to prove?
