white-history.com HELP ME OUT

[I.T.]

On White-History.com is says the Egyptians were White because of red hair mummies. OKAY !
Where did these red-heads come from if they existed in large numbers and when did they enter Africa, displacing the native populations that have been there for thousands of years?
Lastly and most importantly, seeing as how these features are most common in Europe, why would they traverse miles and miles of desert, pass through either all of north Africa (from the west) or cross the burning sands of the middle east (from the northeast), passing up many convenient locations, just to end up in another desert in Africa and halt at the borders of so-called "nubia", just so they can create a civilization before everyone else when they could have stayed home and did it?
