Answer 1

Things like color, shadows, and the relative sizes of objects also help the brain determine how far away something is! Even in video games where both eyes get the same image, your brain can usually figure out depth by a combination of these factors and others. Our brains out wired to assume that things are 3D and figure out how to interpret them using every hint available.
