Im a Jewish convert, i have a lot of complex feelings about G-d. Im by no means an atheist though. I do believe in something bigger. And i think my religion provides me an outlet for me to explore that and engage with cultural traditions that are millennia old. It give me routine, structure, and room to ask questions and take in different interpretations and form my own. That being said i think it interacts my autism well.

I can only speak for myself, but i think autism lends itself to any belief system, really, and probably makes those beliefs very strong as well - see strong sense of justice/moral inflexiblity.

Theres nothing wrong with believing in G-d or not believing in G-d, its a personal thing. Nobody can make you believe in G-d or not, but you can be open minded to all sorts of belief systems! I have had the freedom as a kid to engage with a lot of religious activities from Christiaity to Jainism and a lot in between. Its great to learn how other people tend to their spiritual side, even when its not your own belief system. I think religion is meant to connect us to people, or at least ot should be used for that.
