Atheist Amazonian tribe.

Do either of these groups believe in spirit beings that live above the clouds and sometimes come down and give commands to humans? If not, we're talking apples and oranges.

Are you really saying the clouds are the important factor there, but worship isn't an important factor? Spirits on the ground are just spirits but the moment they are in the clouds they are Gods?

I've met some silly nitpickers in my life, but this has to be the silliest.

Edit: I'm also going to assume that Dr. Everett, who lived amongst them for years, has a slightly better grasp on their beliefs then you do.
