[QUOTE="Arikay, post: 1001044, member: 6561"] It may not only be just earth. As far as our solar system, its been only earth because this planet is best suited, however we have no clue how many other planets have the correct chemicals, just not the correct temp to work. However, it is possible that life or the beginings of life might be under the surface of one of Jupiters Moons. When the probe that is orbiting jupiter is retired, they are actually planing on crashing it into jupiter for fear that if left floating, it could run into one of the moons and screw up the begining life. As far as outside our solar system, we really cant look too well, all we can really search for is inteligent life that uses radio signals. We have only been able to transmit radio signals into outerspace for the last hundred years or so. If you figure life started around 3.8 billion years ago. We have been able to send out radio signals for 0.000003% of the total existance of life on this planet. And we have been looking for even less. So, if another planet takes as long as ours to evolve to inteligent radio sending life, those two 0.000003% windows need to overlap, and someone would need to be looking for the radio signals. So its a Very long shot that we will find anything, even if it is out there. :) [/QUOTE]
