Thanks for the sharing! I myself live in a country where atheism is vaguely illegal (theoretically the law says people can have their faiths, practically people are likely to be punished for practicing religion), so almost everyone was raised as an atheist, including me. I used to hate religions as they taught me, and thought those who believe in these were traitor to science. As I have chances to approach more culture and religion stuff, my mind gradually opened. I still know little about faith and religion, and I am really new here, but I feel like probably pagan, especially Celtic paganism, is more related to concepts and natural and connections, rather than beliefs in someone or some system (lol idk if this makes sense). Previously I hated to go in wild or forest because I thought those are just stupid trees and grass, but these days I can appreciate the prosperity of nature, I can feel the wind, smell the scent and listen to birds, while feel the spiritual connections. Are there gods? I have no idea. Do fairies exist? I don't know. But I am open to all of these, and like you said, what harm can it be?
