Were trilobyte truly interested in science, which obviously he is not, you would need to take him back to the beginning ... whatever that is and obtain a common agreement on the source of C14 in the universe and the relative percentages of C12 and C14.

Your rational understanding of this is based upon an accepted, and thus unspoken, understanding of the basis of the relative abundance of carbon isotopes.

The truth is that trilobyte doesn't know the difference between C12 and C14, doesn't know the origin of isotopes, doesn't understand their relative abundance, and worst of all ... doesn't care that he dwells in the darkness of willfull ignorance.
