I found two interesting articles this evening about ancient pyramids.
The Bosnian pyramids date back 29,200 years!
The Chinese pyramids seem to have been the work of aliens who crash-landed in the Himalayan mountains of southern China. They left records that are actually about the size of phonograph records. This knowledge has been suppressed and the disks are stored in China.
There's much about the history of this planet that is yet unknown.
My interest in ancient archaeology has been brewing many years... and I've written a yet-unpublished novel series set in an ancient land: Antediluvian Adventures.
