Where is it written that Noah and his descendants were the only humans to have survived the flood? The order from God was to take two of every flesh aboard the Ark. Since the Bible is the record of the history of man as it pertains to the line from Adam to Christ. Of course there had to be other survivors, the intent was to drive the evil, and the evil doers from the Earth, not exterminate all but the Hebrew line. I would surmise logically, that on board the Ark were what we call Negroids, Whites, or any other race that existed. How else can you say that there are different “races” without them surviving? In the New Testament, Jesus actually says that the Kenites are the sons of Cain. Kenites are described in the Bible as such. The church of Philadelphia was praised because they taught that this “serpent seed” still existed. He will specifically punish those that say they are “Jews” but are NOT. They are of the synagogue of Satan. Kenites, look it up in a Bible that hasn’t been altered, use a Strongs Concordance, it does help.
1 Peter 3:20
How else can you say that there are different races without them surviving?
What we call "races" are the descendants of Noah, through his three sons, surviving in different environments following the Flood and the dispersion of the nations. There has been plenty of time for these differences to show (although they are certainly not fixed in any way) through natural processes.
In the New Testament, Jesus actually says that the Kenites are the sons of Cain.
Where, precisely, is that?
