"Thanks for all that information on dating rocks, Please note, we are not discussing geology, but Cytochrome c. In this discussion the age of rocks is irrelevant" - TWM
It is very relevant to this discussion because you said:
"What this points to is that all living creatures appeared on the fossil record at about the same time."
You suggest that Cytochrome c infers all living creatures appeared at the same time (I assume in an attempt to justify a belief in the genesis creation account) yet the geology conclusively shows this is wrong. So yes, showing you how other branches of science contradict this thought of yours is relevant.
