Intelligent Extraterrestrial Life

When I look up at the stars at night, I just have to wonder who or what is

looking back at me from some distant planet in some distant galaxy. We’ve all

probably wondered what lies beyond our small, self-contained little world. The

question many have pondered is whether or not there is intelligent life beyond

have planets much like ours, with an atmosphere capable of stabilizing an

environment to a point in which life is suitable. The only reason some think

that there are no planets like Earth is that we have actually explored and

researched very few planets, only a small fraction of the entire galaxy. In

addition to that, scientists believe that our galaxy is a very small fraction of

the universe. A universe which is still expanding, and will continue to expand

forever (ScienceNews May 29, 1999). The number of possibilities for life is

literally infinite.

Before we can discard the notion of extraterrestrial intelligence, we must

consider how much we actually know about the universe around us. While

scientists are fairly sure that no intelligent life currently exists on mars,

the possibility of past intelligent life is still unknown. A two year

investigation of a meteorite found in Antarctica, and believed to be hail from

Mars suggests that life did exist on Mars about 3.6 billion years ago. While
