Ridiculous. The belief that the Earth is less than 10,000 years old is about on par with the
heliocentric geocentric model of the solar system — the evidence is pretty damning against both.
However, as I suggested recently to a voluble evolution denier, they’re welcome to try. The discipline of science is self-correcting, and will shrug off anything that contradicts the evidence, as it has throughout history. You never know, one of these guys might come up with something useful to science despite his beliefs.
