So similarly how can you verify the Earth is round, not flat, most simply without going out into space on a spaceship? View the horizon and note what you can see while standing on the ground. Then climb a tall tree and look at that same horizon. If you are able to see more, then that means there is some angle and curvature to Earth. Literally another example of why one needs to not be focused on a tree and needs to see the forest and horizon beyond.
