There's also an argument that the moon isn't actually a moon since it doesn't actually orbit around the Earth. If you look at their respective orbits, the moon and Earth kind of shift places like a spinning helix pattern and the orbit of the moon is more tied to the sun than the Earth.

I haven't watched this all the way through, but it looks to largely cover the same material. I don't know how common this is among moons, but I think it makes Earth's relationship with its moon that much more special.

Due to tidal effects the moon is slowly getting further away from the earth, so we're living at just the right time to see such spectacular eclipses

There are some schools of thought that say that a large moon like ours should be a part of the Drake Equation, because without which life would have a very hard time even on supposed “garden planets”.

Another factor that is likely to affect civilizations is an easy source of energy, like oil. We got lucky, in that the evolutionary development in Lignin in plants - and the several million years needed for bacteria to catch up and be able to break it down - are what created those massive deposits of organic matter that became trapped deep in the Earth and modified into oil. Without that oil we are unlikely to have reached several milestones, including transportation, population levels, trade, high technology, and even access to space. And this would start affecting us several hundred years back, with steam engines.

WE LIKE THE MOON!

I like to imagine an alien "watcher" with a lifespan measured in billions of years who has been hanging out in our solar system since its formation. It finally decides to contact us humans and tells us that it saw our moon being formed from another planet smashing into Earth billions of years ago. "Yeah, we know - wanna see the movie we created showing it?"

I love that one of the characters in Iain Banks' "Transition" tries to find aliens by spotting airtight -looking vessels (ships, vans,..) during solar eclipses, for this exact reason.

Our moon is only the largest moon to planet ratio in our solar system if you discount Pluto as a planet.

Sometimes I wonder if the moons size / existence is one of the reasons why life is even possible in the first place - Maybe aliens would know what it's like to have a moon a quarter the diameter of the home planet because otherwise life has no chance, maybe life is even more likely on dual planet systems like Pluto and Cheron, maybe that's already too similar in size and life has no chance, maybe the median sentient creature in the universe has experienced a tide, or maybe not - anyways I dunno that much about exoplanets or astronomy in general so every thing I've said might be completely bonkers xD
