It happened in Peru

These local villagers started reporting about some peculiar and menacing behaviors from these off world aliens

turns out, a gang of miners discovered a lot of gold and had devised a plan to scare everyone off the land...
these miners were dressing up in alien suits and even attempted to use jet packs in an effort to scare people.

Sounds like a bizarro scooby doo plot
This would also make for a funny movie

true story people
