Atheists claim that atheism is not a religion. Rather, it is a lack of religion. I see no reason to not allow atheists to define their religious beliefs thusly. However, since atheism answers all the same questions that religions answers, it would be a gaping hole in this sermon series if atheism is left out. So this episode delves into the definition of atheism, related terms (like agnosticism), a rundown of many of the big names in atheism/agnosticism since the Enlightenment, and finally we look at some arguments for and against the existence of God.
