Too many stars:
Darkmatter2525 articulated the argumentum ad absurdum about there being too many stars to believe our planet or Israel is the special center of it all better than I had thought of. He did so by drawing from teleology (Aristotle’s four causes). We totally live in a universe that requires no gods to function, but all religions and their deities seem to have been created to meet the ends of humans. For power and influence over others, and tithes from their fellow man. Occam’s razor says the simplest explanation tends to be the most likely one, and a universe that is not run by any of the gods mankind believes in makes more sense.
Totally wish this video existed sooner. I embarrassed myself by presenting the argument to my philosophy professor after I developed it for feedback, without realizing it was a fairly common argument apostates develop. I still do not know the name of the argument but it is one of the strongest ones. It has become my favorite argument because it is rooted in empirical evidence of the scale of the universe, and logic, and is all encompassing. (I prefer it even over the problem of evil.)
My Mastery of Religion:
I’ll remember it for the rest of my life and never believe any Earthly religion again as a result. There is no need to study religion further for the truth about Gods since I have thoroughly collected the evidence they are all bullshit. The only reason to study religion is to understand sociology, or how religion changes the behavior of people, and how delusions changed history. It also helps to develop critical thinking which is essential in philosophy, except that there are better questions that have not been decisively solved. (Probably well over 70% of philosophers turn Atheist.) Currently I can think more objectively than anyone in the family, and in this niche I know many more facts.
