But the moon size thing isn’t a coincidence, thats part of what makes solar eclipses so rare, the moon needs to be at the correct distance when it passes in front of the sun or it isn’t as impressive, and it does do that some times.

Total* solar eclipses. Mars has solar eclipses, just not very impressive ones since the shadows are so small, but you could actually look directly at the sun to see the shadow at that distance, without fucking up your eyes
