Well, we know for sure that all humans who are alive today do have one male common ancestor so that's a good a sign. As much as I am referencing science and genetics, it doesn't explain why one man's lineage survived to father all modern humans, while everyone else's simply died. If we had all types of humans running around in all four corners of the world, then we simply couldn't have had all humans alive today converging to one common ancestor. It's not possible.Muhammad, peace be upon him, talked about 10 "quroon" between Adam and Noah, estimating Adam lived 10,000 years before Noah. Abraham lived around 100-200 years, suggesting 2,500 to 5,000 years between him and Noah. There is no info on time between Ibrahim and Moses โ could be 1,000 to 100,000 years. If true, timeline could be at least 100,000 plus years from Adam to now. "Quroon" might mean a super long time, like an "eon" or age.

There's so much mystery.
