[FONT="]Why would the alien travel in person? If the aliens have developed such advanced ways of transport why wouldnt they design some sort of android that could make long journeys, over many years and then come home. This is very important. If any sign of aliens will be encountered it will probably be a robot instead of a green man. [/FONT]
[FONT="]If we would see an alien, would we see a green man or an astronaut? Living on another planet without a survival suite is nonsense. Even if the conditions would be similar there would be the need for such a suite only out of precaution.[/FONT]
[FONT="]Could a space ship be captured? It is idiotic to think that a highly advanced creature, that traveled vast distances at great speeds, or using alternative means of transport, would crash their ship when entering our atmosphere. It is like driving around the world and damaging your car while parking at the destination
in such a way that you cant drive it no more.[/FONT]
[FONT="]If the aliens have visited us, wouldnt it be a dangerous situation for us? Many times in our history when two civilizations encountered each other a war was imminent, or one would try to dominate the other. And this is valid when the encounter takes place between members of the same species. If a highly advanced alien would come in contact with us, it would see us no more different than we see a mouse. [/FONT]
[FONT="]But wouldnt the aliens use a scientific approach? When considering a highly advanced creature we can also think about, lets say, a responsible environment approach. This is why a scientist works in a controlled environment and uses surgeon gloves when tampering a specimen. He doesnt want to put his finger in the dish thus contaminating it. So, if aliens are here we wouldnt be able to see and capture them, just by the fact that they would want to operate without interfering with their subjects.[/FONT]
[FONT="]I still havent answered one question: why would they come? In the case of a greatly advanced creature, it is clear for me that they would have passed the stage of gathering wealth, building expensive homes, buying fancy clothes and trying to imitate their celebrities. They would dedicate themselves to knowledge and the universe would truly be the final frontier. The knowledge of space and its mysteries and also their inhabitants would be the greatest achievement that such a creature could desire, improving their condition by perpetual discovery and learning. But they would do it in a very professional manner, going unnoticed and not interfering, certainly not by crashing their vehicles in our planet and walking butt naked out of their ships.[/FONT]
