If the moon had ancient volcanic activity and thus, why is it, after observable impact from various bodies - shown in the craters all over the surface, and the sumizing of the fact that water was deposited to earth from extra-orbital impacts... does the moon have zero water or atmosphere? Where did water originate? (I didn't know how to format that question any better, so please forgive the fumbly format)

The moon's core isn't made of the swirling molten iron dynamo like Earth's is. No swirling molten iron, no magnetic field. No magnetic field, nothing deflects the solar wind that then, literally, blows away any fledgling atmosphere. It's believed that Mars' atmosphere was considerably more dense than it is today, but along the way, its core cooled, and it lost its protective magnetic shield, allowing the solar wind t…

Even with a magnetic field, would the moon's gravity be sufficient to retain an atmosphere?

Treaties on Earth have very little meaning. They have zero meaning on the Moon.

On the contrary... https://en.wikipedia.org/wiki/Treaty_of_Tordesillas Look at that line, and note which non-European countries speak Spanish and which ones speak Portuguese. For instance, Brazil wound up being Portuguese (a rarity in South America) because it stuck over the line into Portuguese turf.

No, for that matter Mars doesn't have the gravity to retain an atmosphere either. I can't cite a source on this because I don't remember where I read it but I believe having a magnetic field surrounding a celestial body is a relatively minor factor in atmosphere retention compared to mass. If someone who specializes in planetary atmosphere retention knows better feel free to eviscerate me.

>feel free to eviscerate me Off topic but I’d like it quite a lot if people could be informative without being eviscerating lol. I suppose this doesn’t usually happen, but it should happen more. That’d be so much better, so much more tolerable and happier. It’d be good for all of us probably lol.

We'll see how much those words on papers mean when real value is to be had up there.
