The pseudos claim that man originated in Africa but this borders on
the impossible when, up until a few thousand years ago, the various
races of mankind were distinctly separate.

The redmen in North America, the Orientals in the Far East, the whites
in Europe, the blacks in Africa . . .

It is absurd to believe that man, if indeed we originated on earth,
could change colors like a chameleon. There might be minor changes
due to various factors but it's absurd to think that it could've
caused a distinct difference in skin color from red to yellow to white
to black.

Duh. You have your chronology entirely backward. Man evolved in Africa and,
over the course of many hundreds of thousands of years, spread first into
Europe, then Asia and North America. Most racial differences evolved to deal
with the differences in climate.
