Because it's called line of sight and there's enough experimentation here on Earth to tell you that the Sun is bigger than the Moon.
Put a 100 ft cube 200 ft from you. Now put a 40000 ft cube 80000 ft from you. I bet if you look directly at that 100 ft cube, you won't see the 40000 ft cube behind it.
You can do this experiment with any small and large object from decent distances. Even a thermos and a vase.
Because. You know. Science.
But but but....that's white people science....it doesn't apply to black people...the laws of physics and nature are different to us....
