If they found a perfect homo sapien skeleton that predated the oldest neanderthal, I would be so FREAKING excited I would not be able to contain myself. I would hungrily read every morsel of the information, I would rewrite the narrative, I would be ecstatic that new information has been found to further explain evolution. It would be quite exciting. I would not hold onto an old understanding, not at all. That is the difference between science and religion. New information doesn't scare science it enriches it. Change is welcome and common. The entire "belief system" doesn't smash to the ground, it just grows. For those that believe in creation, any evidence to the contrary would completely tear it down. It is not exciting, but satanic.
PS, you believe in evolution so I suspect you too would do a little dance if a stunning find like that ended up in the book.
