Since all the evidence contradicts the biblical creation, I'm assuming you just read Genesis. Only the entire bible is finite. Does that mean that if I've read the bible, I'm just as qualified as any other creation scientist?
You'd better know your stuff, if you're going to 'just read Genesis', then come here to debate Creation.
Take this first sentence you made:
Since all the evidence contradicts the biblical creation, I'm assuming you just read Genesis.
The first thing I noticed is that you said 'Genesis' -- you did not say, 'Genesis 1'.
This is a big mistake that, in my opinion, even seasoned creationists make.
One should never go outside Genesis 1 -- for any reason -- when debating the creation week.
Even if they get you into Genesis 2, the debate is over.
Again, in my opinion though.
What about the creationist accounts of religions other than Christianity?
It depends on what point to want to make with them.
If you want to say Genesis 1 is just as valid as any other religious text, but you're an atheist -- then I usually counter with, "What difference does it make then what text you use?"
If I had a box of colored widgets, and I said only one color, blue, is the true color; and someone came along and said, "I believe widgets don't exist" -- then
any widget I pull out of the box would pwn his statement.
Do I just read their holy books?
Again, it depends on what point you want to make.
If 1000 different books speak of 1000 different gods creating the universe in 1000 different ways, then someone coming along and saying, "I don't believe in creationism" is going to look 1000 times wrong in the eyes of 1000 people.
