Sorry, I don't have time for a 38 minute video. But atheism is not about proving there isn't a God. It's about simply taking an evidence-based stance and saying that you won't believe in something just because mommy and daddy and society says it exists. The burden of proof is on believers to show that something as extraordinary as God exists.
Just to be clear, I'm agnostic, but essentially atheist concerning the God of the Bible. That's because I learned about how the Bible was written and now I can see the seams very clearly. It's very much a collection of disparate writings that were edited and mashed together over the centuries, and you can actually see the concept of God evolving from the earlier texts like Gen. ch. 2 to the later texts like Gen ch 1. So for anyone who's actually learned this stuff, they can't believe that the Bible is God's Word anymore. That doesn't mean God doesn't exist, just that he hasn't revealed himself by inspiring the Bible.
