What hard cold facts do atheist use to "disprove" creationism?

I would really like to know what facts (and examples would be nice) of to how people try to discredit God's word. i have looked very deep into creationism vs evolution and the big bang and i could not find any hard evidence that the theory of evolution and how we got here, being more then just a theory. Am i missing something? Because as far as i know, the bible is the ONLY book EVER to 1) be written over the course of about 1600. 2) have 66 books that were written by 40 different authors (most of them didn't know each other.) 3) is historically accurate and has no contradictions but yet the whole thing speaks of one topic. God exists. Honestly i advise you that before you start telling someone that there is no god based on only what you think/know then that is bias. you could at least read the bible to know what we are talking about. i'm not trying to be mean, i just hate it when people are bias and try to talk about something that they themselves haven't even got into to challenge what they think /know.
