Do you think that, if more people continue to meet and love each other, in the end all the people on Earth will be related to each other?

They already are. If they were not, we’d be different species.

As for God, supposedly His Book has this part about the first two people, and then their children…

Adam and Eve begot Cain and Able, and on and on.

Genetic diversity is a good thing.
As long as travel and migration is encouraged we’ll see the melting pot spread and IMO it can’t come soon enough.

Science affirms that all humans share a common lineage that can be traced back through their mothers to one woman who has been identified as mitochondrial Eve. All humans ARE related.

Also, the number of any single person’s ancestors exceeds the world population when going back just 13–15 generations—about 300 years. All humans’ ancestral lines have crossed dozens of times in the past few thousand years.

@Yellowdog ” All humans’ ancestral lines have crossed dozens of times in the past few thousand years.” – Not all with all, since most humans have been geographically segregated for a very long time.

That’s true. Since the Civil Rights era, however, we can live in whatever continent we want.
