Mmm, we're talking about neurosurgeon thats about 5 levels above most other neurosurgeons that puts him light years above most and infinity light years above anyone on this board. That being said, he picks up on things REAL quick such as everything you mentioned above. To even remotely suggest he's anything less would be absurd.
He has a knack for complex scientific things placed in front of him, and he can remember a lot, and work under stress.
There are super liberal brain surgeons too

This still doesn't explain why he believes something like "6001 years ago, there was no planet here. 6001 years ago, dinosaurs hadn't existed yet.
I think BECAUSE he is so smart, he KNOWS what rock erosion and fossils are, and how they got there.
So it's like... you're making my point that he's very brilliant, but truly and completely LYING to people when he talks that "6000 years old" stuff. Do we agree?
