FYI gluadys, IAJ rejects nearly all physics and chemistry due to radioactivity, all geology period, and nearly all biology due to the rejection of evolution and genetics. His big argument against all natural sciences is that nothing has been discovered prior to 3100 BCE indicating writing. He simply implies that without writing there can be no speech.
Of course that belief is against the current state of knowledge in linguistics and archeology, but if one rejects physics, the rejection of archeology or linguistics is not much of a leap toward even more ignorance.
