Aratta (now the area of Donbas / Crimea in Ukraine): The world's most ancient civilisation.

This is a series of papers and books, detailing the discovery and the various historical accounts, by several ancient cultures describing this ancient (and reported to have been, by those cultures, highly technologically advanced), civilisation that was even more ancient than themselves, the Aratta.
Their civilisation, spanned the northern coastline area of the Black Sea, with it's largest populations being in the Donbas / Crimea, area of Ukraine.
Now, if you believe like I do, that there is a desperate race to gather ancient, high technology, then the war in Ukraine takes on an entirely different flavour!
