Were extinct Pleistocene megafauna harnessed to build the largest Neolithic monuments?

Eric Von daniken’s Chariots of the Gods fascinated me as a child, and I witnessed a compelling UFO in my 20’s, but I recognized early the general lack of critical thinking skills in the ancient alien ‘community’. That is a more benign form of the QAnon phenomenon, in my opinion, but still pernicious because it undercuts belief in science. That being said, I’m posting this as an archeology student and asking for a refutation, if you can provide it. Thanks.

I visited Ollantaytambo in Peru’s Sacred valley, near Cusco, in 2015. I agree that current archeology cannot explain how the 50-100 ton monoliths at the Temple of the Sun were were moved from one mountain to the top of another.

Those stones make me wonder if extinct megafauna were used as beasts of burden and, if so, would explain why the largest stones are always the oldest and predate the Inca. Humans domesticated the camel and the elephant many thousands of years ago. No one has established with certainty how far back they were first used. There were several giant species of both in the Andes and we have very little idea about their disposition or behavior. Imagine an animal as or more biddable than a camel—bactrian or dromedary—or an Indian elephant but twice or three times the size.

There was an enormous span of time, almost 200k years, when humans and these giant mammals coexisted. It’s important to remember that climate change, not human predation, caused the mass extinction. I am confident there were talented people to work out the details if it were possible. (Catbyte posts videos of such people just about every day.)

Probably only a single species, one that was endangered already before humans made contact, or a few select individuals within that species, perhaps orphaned individuals, were suitable.

In the past few years we’ve learned that the process for canine domestication started tens of thousands of years prior to the prevailing estimates—definitely prior to the end of the Ice Age. Extinction of predators may have preceded that of non-carnivorous species, leaving a dying species a brief window, a few thousand years, with no natural predators, and selection pressures toward docility.

Direct evidence for their limited use would be extremely scarce. There must be at least one grave, though, somewhere, or ceremonial remains of consumption or cremation. The animals would have played too important a role for zero direct evidence to exist. Maybe searching for bones and graves along the most probable routes taken would find it.
