Your “theory” and the facts are amazingly opposed. The human race began with one man, Adam, then one woman, Eve. After many generations, God became disgusted with mankind’s lack of allegiance to Him, and he reduced the world population to eight: Noah, his wife, and their adult children and spouses. Humans have been rebuilding from there. If you want to truly study both history and science, I recommend you begin with a serious reading of the Bible, cover to cover.
that is well actually...impossible God created ALL the races (black, white ect..) in their different lands, and THEN he created Adam and Eve, and IF you will read the story of Noah, you will find that God said to save two of EVERY flesh, He wasn’t just talking about animals.
