So this sounds weird, but think about it. Everyone is free to have their own religion. So why not be creative and make it an art?
The 5 "rules" that define when art is religion and religion is art are the following:
1. You make up something, a story, an idea
2. It must not be based on lots of evidence
3. It must be hard to prove wrong
4. Use your imagination!
5. Extra points: This makes it a true religion. However this is terribly hard. For this, remember rule 3!
if you are able to do all this, you have my respect!
