I was just wondering what people's reasons were for being an atheist or why they don't believe in god.

My personal reasons are that I can't believe that there is a person or "god" that is controlling the world/universe. How can that be possible? I believe in science and fact and the fact is that the universe was created by the Big Bang. We have actual proof that that happened, not that god created the earth. Any ways, how could someone know that the earth was created in 7 days because (according to that theory) no one was alive then.

Another reason is that I can't see how an all powerful god could let millions of people die like in the Holocaust or epidemics. How could a god let babies die and people get cancer and get raped? That physical and mental trauma that occurs because of those scenarios is unimaginable, so why would a god let people go through that.

I don't like all the bullshit excuses that "god has a plan for us all" or that "everything happens for a reason".

I think people need to wake up and see what reality is, yet I am understanding that people should be able to believe in what they want because I don't like when people put me down, give me grief, or try to shut me up when I talk about my beliefs.

So...what are your reasons? :)
