Fellow atheists, what alive religions (still practiced to a significant degree) do you find fascinating, not including Abrahamic ones and Hinduism? Are the reasons ethical, aesthetic, or something different? I'm excluding these two categories, because they are the answers of most people in English-speaking online spaces.

My reason for asking this to atheists and not all nonbelievers is because I wonder what religions pique the interest of people who don't believe in anything supernatural.

Edit: I was tired when I created the post, and accidentally wrote Hinduism. I meant Buddhism.
