Yeah I think the impact that created the moon is the main reason why there’s life on this planet. That impact also mixed up the heavier metals and liberated enough phosphorus making the composition of earth’s crust unique. Also the two metal cores fused and made it oversized, prompting the difference between the rotation of the Earth and the core, making the magnetic field that protects our atmosphere possible…
So yeah, I’m definitely not optimistic about life on different planets…
And I’m sure the strong tidal pull likely had an accelerating effect on the early stages of the emergence of life, since the first steps would have basically had to crash into each other in water without having any other way to move. There are many other ways for that to happen on the “millions of years” time scale, but the amount the moon moves our water has got to have had a notable effect.
One of the current theories of life formation involves thermal vents, which provide energy and motion (and necessary chemicals) without any need for lunar tides.
Yeah, I suppose I could have made a list of the various other ways, like the water cycle, thermal vents, and the effects of surface level winds on water below the surface too. But even given all those methods, anything else that helps move water around faster is gonna have some effect.

Earth is and always has been the giant beaker of chemicals that has one of those magnetic stirrers in it, thanks to the moon.

I believe there is but it’s also kind of unnecessary to think about it since regardless of where it is past Mars and Venus it’s unreachable anyway.
