Also by mDNA studies, anatomically correct humans (US) have been around for 300,000 years. How many civilization could have risen and vanished in that time (most artifacts would be dust after 10,000 years)? How many could have achieved space flight and left Earth to avoid one of the many catastrophic events during that time period?
I consider the possibility of prehistoric advanced civilizations a real possibility. Rising oceans and earth and climate changes tend to obfuscate the evidence.
Most modern scholars are not even looking. One of my favorite examples is the archaeology site of Göbekli Tepe. It dates as far back as 11,000 years ago; it is a massive megalithic site. Scholars say it took hunter gatherers at least a millennium to construct the site.
OK... What did they use as site plans? How did they keep records of construction parameters? How did so many people hunt and gather while exercising skilled labor duties? If it is a religious site, were there religious records? How were food supplies provided for so many workers by hunter gatherers {they had to constantly move to provide for their families}?
These sorts of questions can be multiplied. Scholars just make acceptable proclamations without any thought to practical considerations to meet their theories.
Look at the megalithic site of Macchu Picchu - supposedly built by the Inca whose 'Empire' lasted about 100 years - along with a huge empire of roads and central administration and cities and temples. The timeline does not necessarily fit the great achievements of a society without the wheel or a written language.
