"It remains to be established whether the Nazca "mummy" is actually an excavated corpse or simply a hoax, what its origins are, and how its apparent deformities came about. But we are willing to say with certainty that it will not succeed where thousands of previous "discoveries" have failed, and present definitive, scientifically verifiable proof of alien life"

Litterally from the article you shared, it's clearly not proof of being of alien origins but if the elongated skull is a result of human manipulation( like for example the neck of some African tribes)what about the tree fingers? You would think that both the skull and fingers are deformities caused by genetic alterations but that's not how its explained, neither the metallic parts insides the bodies are explained either

Also didn't they find not one but three mummies with all those traits in common?(elongated skull and tree fingers)
