  2. What about the possibility of other intelligent species in the universe? I know we haven't discovered any yet but that doesn't necessarily mean they don't exist. After all we've only covered a small area of space. Plus there's a possibility they're hiding from us. Finally if they're more technologically advanced than we are and are capable somehow of traveling faster than the speed of light we might not even recognize their technology. They could fly right past us and we wouldn't even know it.
