Hello! what is the definition of an alien? God, angels, demons, and whatever other spiritual creatures are ALIENS!!! Richard Dawkins is right but he doesn't understand the true implications of his own answer.

Don't we already have technology dedicated to providing power from temperature shifts? These are the same chips that Texas Instruments has thought about putting in the back of the hand or the forehead where the greatest temperature shifts take place on the body. The moon would be a great place for this type of technology. lol, imagine a giant tube installed through the center of the moon designed so that one side is always on the light-side and the other on the dark-side...the lunar ying-yang.
