Stars

While watching a documentary on human development showing homo sapiens started about 300,000 years ago but it is only in the past 10,000 years that human like activities have taken place. Going a step further in is only since the industrial revolution which began about 300 years ago that significant progress has been made. If the human race continues to increase mentally it seems that anything may be possible. When the subject of intelligent life in other parts of the universe comes up most people agree that the distances between stars and galaxies are too great for earth to have visitors. However when the possible age of other civilizations is taken into account the distance no longer seems like a barrier. It is not only possible but likely that there are civilizations out there that have been developing for hundreds of millions or even billions of years since some stars are many times older than the earths sun. It is possible that ways of traversing these great distances have been developed that would allow visitors from far off places, if they desired, to reach earth. When scientist are questioned on this matter they answer in the acceptable scientist way by saying to the best of our knowledge travel between stars is not yet available.
