Exactly. These are obviously the bodies of humans' genetically-engineered descendants from the far future; they've somehow traveled backwards in time to more than a millennia ago where some tragedy befell them and their corpses were preserved until the present day.

Human stupidity is the fifth element. Its on the rise. We see, rarely seen manifestations of it.

Is something big happening in Mexico so that there's a need for a distraction like this?

I saw something similar occuring in my country. When the newspapers report about a scandal, a new distraction is created.

I doubt it?

Not every alien story is a psyop meant to distract people from "the truth." It's just a goofy story for clickbait.
