 I think so. I think there's life like us elsewhere, but there's no way to know yet. People have been listening for signals from other places through the SETI project, the search for extraterrestrial intelligence. So far, nothing has been noticed that would tell us that there's life elsewhere. We know that we already have technology where we could send messages across our entire galaxy, and people like us that knew to listen would be able to pick up the messages. But there's nobody over there with the right equipment pointing at us that we know of. So we didn't already have a chance to change the information. So they could be there, and we would never be able to find them. But my guess is that it's pretty rare.
