There is a White monolithic head, in the science fiction movie Promethius, that is styled in the same manner as the negroid feautured giant Olmec head that was discovered in Mexico. This assuption that the creators were white European featured beings is racists , and is historically incorrect , and misleading. The facts remain, the Olmec head found in Mexico, has Negorid, black features, not White, European features. The enginners were Black. This black fluid in the movie is very strategically included.
