Why we live on earth and not to live on mars
1 Sep 06
For thousands of years, mankind never doubted that life existed anywhere except for on Earth. Yet as humans learn more about the world we live in, we are beginning to ask questions about what exists in the world beyond Earth. Exploring the moons and planets has been around for centuries, but only in recent years have people been able to study the solar system close-up. Now we have technology that allows for scientists to travel to the moon and study planets from spaceships that are able to land on, or orbit around, them. With the advancement of technology comes the advancement of new knowledge about the moons and planets that have been a mystery to mankind for so long. Every year, planetary scientists discover more evidence of a very complex solar system. A question that has plagued scientist for years is the driving force for many scientific explorations of the planets: Does life only exist on Earth? Are we alone? Until recently, it seemed highly unlikely that life existed anywhere except for Earth, but shocking discoveries on the planet Mars has given scientists new hope in their search for extra-terrestrial life.
