As jody foster once said, it would be an awful waste of space if there were not others. I feel they are there. Our universise is expanding, each planet and star moving more away from each other and faster too, not slower. It would be hard to space travel, but I do believe there are others who can. The universe is very old and had time to develope civilizations. So much we don't know. If our planet could stop warring with each other, gosh what we could learn. All countries have their war memorials, don't we get it yet? I live on the fla. coast. I am worried about our gulf. We would also solve so many of our medical conditons if our strengths could be put into medicine. just a thought or two. ginnie
