I have often wondered how history might have been different if the moon were covered in greenery and blue oceans. Since we can see the moon's shapes and craters with our naked eyes, I imagine that we might have seen weather features and clouds too. I wonder how human history might have gone if we could see a changing, living world up there every night.
Would be interesting to see if this can be tied to impact events back on earth.<p>Given the gravity of the moon a volcano can definitely blast earth with material.
