True. Mitochondrial DNA evidence proves that Homo Sapiens did not exist before that date, but paleontologists don't want to talk about it. Must preserve Darwinism at all costs.
“The common Y chromosome ancestor lived 250,000 years ago, not 4,000.”
Measuring time is a peculiar thing. If you take a spaceship and go at nearly the speed of light to the edge of the galaxy, and return, it would take you about 40 years. But in that period, about 100,000 years would have passed on earth.
Yet you would only be 40 years older.
I think we can’t measure yet with any accuracy how “old” the earth is, or how much time has passed between events.
No it doesn't. The common female and male ancestors don't need to exist at the same time. They just both have to be common to everyone alive today.
