According to Macroevolutionists, it could be around 60,000 years (60,000 ya go out of Africa and one branch goes to South Asia and Australia and nearby islands while rest stay around in southwestern Asia (Middle East); 40,000 branching in southwestern Asia with one part going to Europe, the other to Asia; and 20,000 ya a group of north Asians go to the Americas?).
However, in the Creationist model, the universe and world are some 6,000 Earth years old. Some 5,000 years ago the global population was wiped out except for one family from which every single human today is descended. Thus, at the very greatest extent, two people could be at most cousins separated by some 5,000 years.
Kudos to all respondees on this thread so far. Only the guy who posted something about leftist nonsense could even be
construed as rude, and it definitely did not seem personally directed.
Evidence that there can be respectful disagreement.
