Were did black people people come from when god flooded the earth when only Noah and Mary were the only ones alive...... I'm only 15 and I want to know?

Noah didn't flood the earth, The Bible is a fairy-tale which is brian washed into you as a child! The video linked below may help you realize how silly this story actually is. There is also loads more videos on there about Christianity and how the stories in the bible don't add up but takes a comedy approach on it!

ANSWER 2:

According to Genesis, Noah was accompanied on the ark by his wife, his three sons, and his three daughters-in-law - no mention of a Mary. That aside, the story of Noah should be viewed as symbolism; however, if it in fact took place, it would not have been a global flood but a local flood. In all probability it took place in the Bronze Age or earlier, when "the earth" would have been considered as far as the eye could see or where it ended at the water's edge. The geographical area where the story took place was somewhere in what today is known as Turkey in the Middle East.

To answer the question about black people, they were then, as they continue to be now, from the continent of Africa and the flood in Turkey would have had no relevance to their existence one way or another.

I think differently. What is the surety that Noah or Mary or any other who were responsible for growth of generation is no Black. Why do you see them as White only. Even Jesus, Adam, Eve could be Black. What we see is only the imagination of artist. Further as per Darvin theory due to evolution Black people would have been given birth to.For example see Mongolian race who are yellow.
