I dont know too much about astronomy, so my question may seem like a dumb one to you guys. I heard that its been speculated that the earth's moon has lunar ice. if it does, then it has water, which is a necessary component for a planet or moon to sustain life, just like if mars had water, it likely supported life. But if the moon has lunar ice, how come no one's really talking about the possiblilty of life on the moon? there all this hype about how mars may have suported life. is it because of the moon's distance from the sun, or what?
