Can I be angelkin if I’m open to the idea and believe there is a deity/higher power but don’t have any specific religion? I pray, but I do not know specifically who I’m praying to, I guess.

I think that’s absolutely fine, anon. As far as I’m concerned, who/what is out there deity-wise is a big mystery that nobody knows *for sure*.

Also, like I said, I fully believe that there are sincere angelkin who are also sincere atheists. I just *personally* think that’s a difficult pair of beliefs to hold at the same time.
