He is a denier, first asks for proof of species changing into other species, proof is shown, he denies it, then he simply goes back to his old roots, thats not evolution, he says, ask him what is the definition of evolution, he doesnt know

All the proof in the world wouldn't be enough for him, he keeps arguing in bad faith and engaging in sophistry.
Half-convinced he's trolling, to be honest.
