I’ll just emphasize this point, even though it is not exactly on topic for this thread, because I think it is often not sufficiently appreciated.
We can come up with a pretty accurate estimate of when the most recent common ancestor of humans and chimps existed from the fossil record. And can also estimate this from the number of genomic differences that differentiate us from chimps (which under common descent would have resulted from mutations) and the observed mutation rate.
The estimates by these two very different methods come up with the same answer.
That would be quite an amazing coincidence if common ancestry was not true.
