Why don't you post some identifying information so we can appreciate the expert you are?
Why don't you...? You *first* made the claim that Carbon-14 dating gives us "billions of earth years"...! High school chemistry and high school physics negates that claim.
Showing someone else's mistake does not establish your credibility.
For *you* to question anyone else's 'credibility' is pretty funny.
My credibility is not the one being asked about.
Nobody here asks about 'your' credibility anymore.
