Note this is about 1000 years old. That's 700 years after the fall of Rome, and well into recorded history in Europe, and yet this civilization was "lost" to us.

The pyramids were built 2000 years before the Roman Empire. How many complex civilizations preceded the Egyptians?

By the way, the Egyptians "lost" the Sphinx for a while and had to dig it out of the sand around 1400 B.C.

"By the way, the Egyptians "lost" the Sphinx for a while and had to dig it out of the sand around 1400 B.C."

The Egyptians didn't lose the Sphinx. They may have discovered it around 1400BC but someone else originally built it about 9,000 years ago acording to Dr Robert Schoch, geologist/geophysist

I think that the evidence is that they are far older than that. I suspect that the 1000 year reference is a typo.

All these civilizations were wiped out by diseases after contact between the "old" and "new" worlds, but were already very old at that time.

For a group desperately seeking archaeological credibility, dates are a minor detail.
