I would say that it takes a lot of faith to make a statement such as Neandertals didn’t use projectile weapons...

That's the evidence to date. I agree that they can't actually know.

That’s the interpretation of the evidence. There could well be others, and probably are.

As an engineer, I’ll interested in how well their theories predict future, so far undiscoverd evidence.

Off on a tangent now, did Neandertals have souls?
