This is starting to fit more in the science forum, so I will keep it semi short.
"I've seen evidence that proves a global flood."
But does it stand up to scrutiny?
"to name one resource where fossilized bones of saltwater fish are found embedded thousands of feet above sea level..."
But, some important questions.
Do we find fish fossils on all high mountains? (no)
Could a changing earth push dirt and rocks and fossils from the bottom of a sea and form them into a mountain? (yes)
Are all the fish fossils modern or ancient? (ancient)
We would expect opposite answers if these supported a global flood.
"I've also read (and I'd have to try to look it up again) that most cultures, not just the Christians trying to prove the bible is right and literal, have some sort of "flood" myth in their history."
Three interesting things about this,
1) Not all cultures have flood myths. However, many cultures were built along water ways and seas. Some even built their agriculture around a annual flooding (egyptians). Because of this, we could expect that Flood myths would be common.
2) Many cultures had a flat earth myth. Does that make it true?
3) This is the most important point. This is good evidence that there was no global biblical flood. See, if the flood happend like it was supposed to, there should be No other cultures around, Everyone except for 8 people should have Died. Entire cultures should have stopped. But they didnt. They continued. Not only did they continue, but they continued with no interuption and no record of a world wide flood. (this is of course assuming you are using the Ussher biblical date of the flood).
Like I said, this is more for the science forum, so here are three things that I have written and saved about the flood,

A look at a couple YEC flood models,

Creationism as science (a look at the predictions I mentioned),

For more information about the global flood or its falsifacation, I would recomend looking at the science forum, there are many good posts there, like for example, Frumious Bandersnatch's Biogeographies post.
