"....diamonds supposedly millions of yrs old registering radio carbon."

Again, not heard of this so can't comment. Did you get it from a creationist source, pete? But even if it's true and even if it casts doubt on the science behind radio-carbon dating (which I doubt) then it says absolutely nothing about the validity of the creationist viewpoint. Again, for the umpteenth time, you can't just insert God into the gap that you think you've spotted!
