Its not at all debunkable. They called themselves the Black Headed people. That "Black" keeps popping up doesnt it? The farther you go back the Blacker the world becomes. Like the Greeks and other historians say. Blacks ruled all the way to SE Asia.
"It seems certain," declares Sir E. A. Wallis Budge,
"that classical historians and geographers called the whole region from India to Egypt,
both countries inclusive, by the name of Ethiopia, and in consequence they regarded all
the dark-skinned and black peoples who inhabited it as Ethiopians.
"Apollonius Rhodius states that the Egyptians of Colchis preserved as heirlooms a number of wooden tablets showing seas and highways with considerable accuracy. Though this theory was not generally adopted by the ancients, it has been defended – but not with complete success, by some modern writers. There seems to have been a Negroid component (which predates the Arab slave trade) along the Black Sea region, whose origins could very well be traced to an Ancient Extra-African expedition, although this cannot be verified by archaeological evidence."
“In former times this Asiatic Negro spread, we can scarcely explain how,
unless the land connections of those days were more extended, through
Eastern Australia to Tasmania, and from the Solomon Island to New
Caledonia and even New Zealand, to Fiji and Hawaii. The Negroid
element in Burma and Annam is, therefore, easily to be explained by
supposing that in ancient times Southern Asia had a Negro population
ranging from the Persian Gulf to Indo-China and the Malay Archipelago.”
-Sir Harry H. Johnston
“Back in the centuries which are scarcely historic, where history gives
indeed only vague hintings, are traces of a widespread primitive civili-
zation, crude, imperfect, garish, barbaric, yet ruling the world of that
age from its seats of power in the valleys of the Ganges and the Euphrates
and the Nile; and it was of the black races. The first Babylon seems
to have been built by a Negroid race. The earliest Egyptian civilization
seems to have been Negroid. It was in the days before the Semite was
known in either land. The black seems to have built up empire, such as
it was, by the water of the Ganges before Mongol or Aryan.
