Civilizations of the Previous Age

Why do you think they were humans? The Sphinx in particular was built by lion people.

Civilizations leave evidence.

Pottery, sudden replacement of indigenous flora and fauna with domesticated species, worked metal items.

We have evidence of stone tools progressively getting better and better until the neolithic revolution.

It wouldn't make sense that genuine civilizations existed without domesticating animals, firing clay, or forging metal.

It wouldn't make sense to humans*

Nabta Playa is a part of the greater Aqualithic of Northern Africa. I have a thread discussing the Neolithic Subpluvial here

Well OP did say an age of humans

no evidence, and because of how recently it would have had to have been, the absence of evidence in this case is evidence of absence. they would have had to have an active agenda to remove evidence of their existence to have existed.

it's more possible that there was an intelligent species millions of years before humans, as evidence of their civilization would have long been destroyed geologically. there is little reason to speculate on this, though.

If civilizations leave evidence, then wouldn't these be particularly solid evidence? It was pottery and fire pits which led to the discovery at Nabta. Perhaps it is an error to measure their civilization by our standards.

They were compromised with foreign DNA so that only one family on earth was pure human.

We're getting pretty close to the same exact condition.

This is a valid explanation of their creation, but I feel at this point in our current age of human development i.g. global culture, potential for interplanetary travel, that it is of critical importance what happened to the last culture of creatures on this planet capable of calculating 26,000 years of celestial time.

I wouldn't trust people off 20 parts in 26.
