Why do two dimensional maps of Earth have distortions

Because the only way to properly represent places on a sphere is on another sphere.... a flat map cannot properly depict the distances between more than three different places.

Imagine three points on the surface of a ball, all out of 'sight' of each other because of the curvature of the ball. If you draw a straight ling between each of them you would get a 'triangle' whose lines curve around the surface of the ball.

If you measure those lines and plot them on a map, you could transfer each of them exactly - but, if there was a fourth point involved you would not be able to accurately represent the distances between each point and the other three.
