1.realizing there are many, many religions, all claiming to be the only right one, which cant possibly be true. therefore, all others must be man made.
2. realizing that it would be possible for my church to function even without a god, and could therefore be man made.
3. If it, like all other religions can function without a god, then what does god do? does he even do anything? "guides us in our decisions" "gives us authority" like every other religion claims that he does?" no statistical evidence supports the "god" theory, or any other evidence for that matter.
I could go a lot more in detail about specific parts of those, and any reasoning that was involved in those, but that's a basic outline.
