Imagination – The ability of the human mind to visualize/conceive the intangible.
If we had imagination, we would understand that we live on the surface of a giant sphere and not on top of a flat board. The reason Earth appears flat to our vision is because, we are a tiny speck on this planet, which makes us disproportionately small to be able to see the entire size of the giant ball.
Instead of arguing with the scientists, we would be able to verify this fact for ourselves personally, if we were giants towering over the planet, with our head reaching past the atmosphere to be able to see the globe in its entirety. Since we are not, we should probably talk to the tiny ant on top of a basketball, about the shape of the object it stands on, and it would say that the basketball it crawls on, is as flat as a pancake. And of course, we would know that the ant is wrong, because we can see the ball, just the way the astronauts can see our planet from space.
