Back to the aliens and planets discussion.. what about the amount of time it takes light to reach Earth? If we are looking at planets and galaxies that are thousands of lightyears away, doesn't that mean what we see today is something that happened thousands of years ago? We don't really know the current state of these places. Not only would they be different before we even attempted to reach them, but by the time we did reach them they would be even that much more different.
