An Atheist Perspective

What causes someone to not believe in god. Briefly looking at a history of atheism I found that it was it was "founded" in the 16th century in France. I put founded in quotes because I'm sure the idea was around before then, but I imagine that is when it really became a movement. It is interesting to realize that while it isn't a particularly new idea, it also isn't very old. So for most of recorded human history their has been a unified idea that there is a god. Yet in recent history there is a strong current towards atheism. Some attribute this to ungodliness, and some to science, but really it is hard to say. But really an interesting point that I've been thinking about is that while atheism says there is no god, it does not have a say about an afterlife. As far as that belief goes anything could happen once you die. Just interesting to think about.
