are aliens black

i think we all did read the book of yakub which states the black race hails from an ancient civilization from the sun and which then yakub after being ostracized created the white race BUT then that means were aliens black? maybe the aliens were another color like blue and shit and when they came to earth their disposition adapted to the weather THUS further proving the unnaturality of the white race as it had to be engineered by a scientist as nature would not produce such abominations
