Can you tell me why you do or don't believe in god?

I'm an atheist, I don't believe in God ... or Gods for that matter. I used to. I grew up in a roman catholic family. Our community was very church oriented, and our family even more so. I was part of the youth group, church choir, volunteered to help at retreats, and followed along like a good little christian. Until I started asking questions and no one wanted to answer them. I was eventually told to stop asking, because doubt is a sin. When I left home, I started finding the answers on my own. I read the bible several times over .. studied it outright. You'd be amazed how many christians have never read their own bibles front to back. I read religious history texts, studied everything I could in regards to religion ... christianity admittedly more so. And the conclusion I came to was fairly basic. My mind works in terms of logic, facts and evidence ... none of which can be found in support of a God. So I chose not to follow the crowd and come to the conclusion that made the most sense to me on a logical level. There is no God. The entire idea of a god was created in a time when people needed answers, and science wasn't yet at a point to start answering them for us. So people created the idea of a God. The problem is that once science began to catch up and actually answer those questions, the church fought against it tooth and nail, because it contradicted what they'd been teaching. Science proved that the earth revolved around the sun and not the other way around as previously believed. The church denied it, imprisoned anyone who said different ... only to turn around years later and admit it was true all along. And religion still wants to halt science at every turn ... stem cell research for example. No, I don't believe in God. I don't believe in God for the same reason that christians don't believe in Zeus, or Mithras, or Isis and Osiris. History has had many Gods, depending on the culture and civilazation. And not one of them has any more evidence and proof backing it than another.
