text: what if they found life on another planet in another solar system, & the life form is a duplicate of us? scientists and astronomers tend to believe we have an exact duplicate of us somewhere in the universe. what do you think? could we switch places with them? well, since the universe is infinite, and contains everything, then everything you can dream up has happened somewhere; i'm certain that there is another earth, with identical people, places, things, etc, if not in this universe, than in an alternate.
