Creationists researchers are also able to provide evidence of creation, a deceent back to 2 individuals, and no common ancestor with any ape. It does not matter that this evidence is refuted by evo researchers as they refute each other all the time yet still manage to agree 'it all evolved'.

This doesn't have anything to do with the MRCA between humans and other apes like chimps and gorillas, but I believe you mentioned this as part of an argument that scientists are all over the place regarding human ancestry and really know very little concrete. While I was able to find that there are disagreements about how fast the molecular clock "ticks", I wasn't able to find anything indicating that conclusive evidence for any particular figure, such as your claimed 6000 years, had been uncovered.
I think many scientists would agree that there's insufficient basis for claiming any particular date for mitochrondrial Eve or Y-chromosome Adam. Certainly the Wikipedia article on
Human mitochondrial molecular clock supports that view.
It would be fascinating if 6000 years ago as the time of the MRCA were nailed down as the correct figure, but realize that MRCA stands for the
Most Recent Common Ancestor and not for
When the Species First Appeared. In other words, no matter how long ago the MRCAs, they weren't the first humans.
