Ask An Atheist Round 4
It's that time again. Today is national Ask An Atheist Day (well, technically it was yesterday but derpity-doo). So, you know the drill. I'm an atheist. Ask me anything. To my fellow atheists, please fill free to help answer any and all questions. This challenge isn't restricted to me to answer questions. This is an opportunity for all of us to learn one another. And I cannot stress this enough, please try to be respectful in your questions and comments. Thank you.
I hadn't been planning on entering your challenge, but I am a curious human.
What convinced you that God, or anything else dealing with spiritual beings and the such, were not real?
