as an epistemological solipsist i have no way of knowing religion even exists, let alone want to believe in it

Sounds like you just randomly picked something that "sounded cool" from wikipedia without knowing what it means.

Then in the same sense, you could say anything in the independent, real world may not exist and thus you would not need to believe in it. An epistemological solipsist could also say that there is no way of knowing nature exists, let alone want to believe in science.
