I don’t think we will ever see aliens in our lifetime. However, the aliens will come to us to check up on how the world is right now. They will be very disappointed. I love the world, and in some places it is a better place to live at. But, saying that to the aliens they won’t think so. They will think that we have disappointed them. They are going back here to see the results of planet Earth. The aliens won’t see a pretty sight. Most of us will, but not them. They are hoping that the world will have a peaceful progress. Therefore, none has come to that point. Once this civilization is over they will decide whether or not they will start another. I think to me most likely they will say no. But, it may be that they would start another one, but this time they want the other world to solve their problems, rather then making new ones that won’t ever be changed. Let’s hope that another civilization comes after this one. Anyway, they always will come here to check on us and the planet Earth, too!
