> Our eyes only ever see 2D images and we learn 3D structure from that

I think that would be an oversimplification. We do have some 3D information from focus and eye convergence.

its not an over simplification. The extra information from convergence is negligible... our eyes derive virtually identical information when looking at flat 2D pictures of 3D scenes. Evidence of this is everywhere in pictures.

I'm sure people born with one eye are perfectly able to understand the concept of 3D

Dunno if you fully read my comment. But we're in agreement.

You're right, we are in agreement.
