I personal y think that he did because extra terrestrials must have their phone billing system. They have big spaceship that take their kind all over the galaxy, so they must have a long distance communication system that is very cheap and efficient to use over long distances. ET's kind is thousands of years better than our tech , so they must have cheap and quick communication. The thing on his hand must obviously be a high tech phone that costs him money, because lifeforms just don't have those adaptations, no matter where they live. Please vote for me.
