The modern ones are specific to the Pacific indeed. And there was no violence involved I assume. But that's also because they were remote areas that had limited or no contact with outsiders
It makes you wonder how things like the rain dance evolved. They even wore different clothing to engage in this activity, so it could have been because they've seen other people do it and eventually it was spread out to more tribes. I haven't come across anything that suggests a connection between the religious outfit and the common outfit of another civilization but there's not much to go with.
In Africa they probably despised these large ships and later on the metal beasts on both ground and air as it was a sign of doom. No idea if anything like that is imprinted in any African tribal cult which is something interesting to find out.
No part of Africa was ever isolated like the Pacific islands were, and always had technology close enough to the others that the appearance of outsiders with slightly different things than they usually used wasn't that surprising.
