In my secondary world, one of the main religions is a vague medieval Christianity. Of course, there are differences made for it to fit in with the lore, as well as a few other major religions. After trying to write it down, and thinking about life on other planets and world's, it got me thinking about the forming of religions. In history, there are many coincidental similarities from separate cultures, like the pyramids of the Aztecs and Egyptians.
Theoretically, how likely is it for a religion in a different world, or planet for scifi, created by a otherwordly or alien society, to be almost exact or coicindetaly very similar to a religion here? Notes to add:
- There are similar biomes
- Geography is similar
- The planet has the same qualifications as Earth
- The environments follows the 7 rules for a planet to maintain life.
- Aside from fictional monsters and entities, the rest of the wildlife is normal.
- While deities do exist, they do not control or exactly create the universe, as some of the religious lore is either exagerrated or misinterpreted
