There is no evidence that it's an alien either, and yet people claim it is.
Yes, yes we can say for sure:
FACT CHECK: Did Researchers Find a Mummified, Three-Fingered Alien in Nazca, Peru?
"In 2015, Mexican journalist Jaime Maussan, who reported the existence of the Nazca mummy to Gaia and is featured in the video, led an event called Be Witness, at which a mummified body — purportedly that of an alien — was unveiled. Later, though, that “alien” discovery was debunked, and the mummified corpse was shown to be that of a human child.
Forensic scientist José de Jésus Zalce Benitez was one of the lead researchers behind the (debunked) 2015 discovery, presenting his findings at the Be Witness event. Benitez also took part in Gaia’s Nazca project and can be seen in the video claiming that the three fingers of the mummy “makes us think that this does not belong to a human species.”
Interestingly later in the article it appears that Gaia were the same people claming the elongated skulls were aliens too.
Haha, Gaia is a joke they just try to claim anything they can is an alien.
And ya, that page is about the 2017 video, but the origins of the hoax go back to 2015.
