That's incorrect. There was massive construction of cities that are now underwater in the black area and other areas that are just being discovered. There was widespread construction and material civilization and whites were the original humans and originated in Georgia. Nothing was recorded because writing is Jewish.
Blacks evolved in Africa and created the "official" type of humanity preserved in bureaucracy and historians based evolution on flow of language to create out of Africa. Language came much later than people were able to build things and the underwater cities and destroyed infrastructure from ancient times happened in the 10-20ky gap you mentioned.
Humans committed genocide of neanderthals and that was also supressed and no oral history was preserved (except a neanderthal history which has by now been lost).
The harrapans destroyed all the desultory information about their civilization and everything that happens before the official story is suppressed. In reality humans were building stuff more like 20k bc and before then actively killing and destroying over groups the whole period 20k-100k bc.
