Who are our real ancestors?

The Torah, Bible and Koran claim that Adam and Eve are the ancestors of all humankind. This claim has distorted Africa's history. What really is the truth? The sciences of paleo-anthropology, radiometric dating, MtDNA, Y-Chromosome and melanin prove conclusively that we are all descendants of Africans. So why is religion perpetuating this lie and why do so many believe it?
