As for Noah...I agree. All races did not, could not, come from he and his family. And, they didn't...anymore than all races were from Adam.
There seems to be a misunderstanding here: when I say all
races came from Adam and Eve, and then from Noah and his family, I am referring only to
human races- black folk, white folk, asian folk, arab folk, indian folk, etc. etc.
I maintain that all
human races present on the earth before the flood
did originally come from Adam and Eve. And then again, all
human races after the flood (which means all the
human races we see today on the earth)
did come from Noah and his family.
If we focus on Noah and his family, I am saying that at some point after the flood, the genetic make up of one of Noah's descendants changed- and a child was born that "looked" different than Noah or his offspring- and that difference was genetic; that is, when that child grew up and married and had kids, the children also "looked" the same as one of his parents, and totally different than Noah; a new race of people had begun.
That pattern continued- generation after generation, every new child had the same overall genetic make-up of its parents and "looked" generally the same- that is, was the same race as its parents.
But then at some point, there was a mutation (remember- this only means a change in genetic makeup- it doesn't imply something bad) and another new race began. Fast forward to the present, and this process of human evolution explains why we have the multitude of human races that we see today.
Genesis 6:18-19 But with thee will I establish My covenant; and thou shalt come into the ark, thou, and thy sons, and thy wife, and thy sons' wives with thee. And of every living thing of all flesh, two of every sort shalt thou bring into the ark, to keep them alive with thee; they shall be male and female.
Genesis 7:15-16 And they went in unto Noah into the ark, two and two of all flesh, wherein is the breath of life. And they that went in, went in male and female of all flesh, as God had commanded him: and the LORD shut him in.
We have been programmed to see
"all flesh" as elephants, giraffes, dogs, cats, lions, tigers, etc walking up the plank to enter the ark two by two. But, is that what is being said?
Yes- that is what I maintain is being said. That is what I believe, and what my study Bible teaches. First, let's use a modern translation of the Bible (the NIV in this case) to help us examine this passage more easily:
Genesis 6:18-19:
18 But I will establish my covenant with you, and you will enter the arkyou and your sons and your wife and your sons wives with you. 19 You are to bring into the ark two of all living creatures, male and female, to keep them alive with you.
I read this to mean that there were only 8 human beings on the ark, and then two of all living creatures (i.e.
animals), one male, one female. But note that the animals were special- since they were male and female, only those animals able to sexually reproduce were present. Also, none of the living creatures in the sea, such as fish, could have been present- after all, the flood wouldn't have affected them.
Correct me if I'm wrong, but you seem to believe that there were more than 8 human beings present on the ark- that all the other human races of mankind (besides those that Noah and his family represented) were part of the "living creatures" that came onto the ark. I don't believe this is the case.
Genesis 2:7 And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
Genesis 6:12-13 And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth. And God said unto Noah, The end of all flesh is come before Me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth.
Here we see
"all flesh" as man and then suddenly
all flesh becomes animals only when they enter the ark.

Flesh with the breath of life, two by two, male and female...were taken aboard the ark with Noah and kept alive. God didn't destroy all the races He created.
He created the "
multitude of races that we see today." And, they were created that way in the beginning.
.
Well, again- there seems to be a misunderstanding- I was referring to the multitude of
human races, and you seem to have assumed that I was using the term
races to refer to all the living creatures on the earth, man and animals.
