"Atheism is more than just the knowledge that gods do not exist, and that religion is either a mistake or a fraud. Atheism is an attitude, a frame of mind that looks at the world objectively, fearlessly, always trying to understand all things as a part of nature. " Carl Sagan No disrespect to Carl Sagan, but he clearly has mixed up the terms 'atheist' and 'scientist'. An atheist is someone who doesn't believe in god. A scientist is someone who looks at the world objectively and tries to understand all things as part of nature. I fail to see how the two are connected, nor can I see how lacking belief in god is necessary to look at the world objectively. Oh, and whoever Christians are not the majority of theists, I think you're wrong. I'm pretty sure aroun 1.8 billion people are christians, I don't think there is a larger religious group. Compared to that around 1 to 1.5 billion are atheists. *puts up hand. That was me. Perhaps you misunderstood what I meant by theist=someone who believes in God. By your numbers, world's population=6 billion-1.5 atheists = 4.5 theists, of which only 1.8 are Christian. So Christians are not the majority of theists.
