Sophisticated life forms are relative newcomers on Earth compared to bacteria or archaea. They arrived later because the Earth proved to be a healthy environment over a long period of time. Because the environment of other planets is more primitive, life on other planets (if it exists) may be primitive and unsophisticated. If not, life would have developed the ability to withstand otherworldly environments as well as finding material for nutriment. We might have to imagine what such creatures would be like.

Non-sophisticated life forms may have an easier time in a harsh environment. Even so, all life as we know it, leave behind certain signs that it has been there. In 1996 scientists mistakenly thought that they had discovered life on Mars. There has not been any concrete evidence as of yet of life anywhere in the solar system besides Earth.

Here we present a look an the environments of some places in the solar system; Mercury, Venus, Mars, Jupiter, Io, Europa, Saturn, Titan, other moons, Uranus, Neptune, Triton, Pluto, comets, and interstellar space.

Primitive life forms may have an easier time in a harsh environment. All life will leave behind certain signs that it has been there. Scientists recently thought that they had found some of these signs on a Martian meteorite, but it turned out to be untrue. No concrete evidence of life anywhere other than life has been found.
