Atheist who is having a crisis of faith

[emilsein]

I need some good logic to convince me to stay an atheist or at least an agnostic. I have been researching the bible and found out that throughout the old testament, well shit, it says that Jesus during his crucifixtion will experience darkness on the earth. And according to historian Josephus and Thailiius there was a weird omen that day. Now NASA just announced that there was a lunar eclipse during his crucifixtion time in a.d. 30, so now NASA is backing it up, not only that they say there was a lunar eclipse when Christ was born, they have been able to narrow it down. So knowing this could be a possibility and there was darkness during it, how do you explain it? How in the old testament, sprinkled throughout the damn thing they make literal prophecy about the earth being dark for hours, then it happened according to NASA. I am starting to wonder if this Christ fella might be real, but I need some logic, I am a schizoaffective type and have bad ocd so I'm writing this and reaching out to the atheist communityj. I don't belive much of the bible myself, I Do believe that he was crucified though and why would josephus  and thalius lie about the darkness? I get the Christians lying but not the others, Does this seem like it might make you believe? How do you explain the old testament knew about the darkness?
