Lets take a little break from politics and have us a real atheist conversation.
Personally, I’m open to the idea of the existence of supernatural phenomena, and I believe mainstream religions are actually complicated incomplete stories full of misinterpretations, misunderstandings, and half-truths.
Basically, I think that these stories are not as simple and straightforward as they seem to be to religious people. I feel like there is a lot more to them. Concluding that all these stories are just made up or came out of nowhere is kind of hard for me.
The reason not to would be that there is literally no evidence for it whatsoever. We do not have to be able to detect it ourselves to get evidence of it. We can’t see atoms but we can build things to detect atoms.
Your “I don’t see any reason not to” can also be applied to the belief in many gods.
