Theists: What is the most compelling argument you have heard for Atheism?

[SteveII]

Getting stuck on one religion misses the point. The arguments for any religion are all the same.

1. My club is  correct.
2. My club has had a long history.
3. My club produces moral people.
4. My club's holy people have insight on the nature of reality.
5. Science doesn't debunk religion.
6. My club has produced scientists.

When religious people cant prove the necessity of their club/holy writing/holy person, they will resort to either attacking science or trying to claim science points to their religion. But that is not just Christians who do that, but every religion in the world, including Jews and Muslims and Hindus and Buddhists. [1]

The reality is that human morality is evolutionary, not coming from books or holy people. [2] The reality is also that our species evolved to be curious, so when any religion tries to claim ownership of science they are simply falsely attributing our natural curiosity as coming from a spirit/divine/god world. [1]

1. I don't remember making any of those arguments, so it would seem you have in your mind an easily knocked over straw man--not an argument or theory that explains the evidence we do have. 
2. That is a theory in which the only evidence is the presupposition of Naturalism.
