"It is believed now that the Inca and Maya both vanished with out European intervention after extended periods of drought and war. "

Even the Inca don't know who built Tihuanaco, it was there as long as they can remember.

I've always thought that the descriptions of the "lost (land) of Atlantis" is best fulfilled by Central South America. Seems to fit in with Tihuanaco...Atlantis being "beyond the world's oceans" or thereabouts, as described, "past the Pillars of Hercules" (something close to those descriptions)...I regard that as being outside the Mediterranean Sea and across the "world's ocean" which was the Atlantic at that time and/or from the East across the Pacific, both would result in arriving in Central South America.
