Potentially, there are billions of locations outside our solar system that may contain life. NASA Mars missions 12 meteorites fell on the Earth from Mars. The life form should be 3000000000 years old and seems to have been similar to terrestrian bacteria. Diameter 6794 km. Seasons similar as on Earth.
Much water is hidden however underneath the frozen surface and in the polar regions.
Probably 3000000000 years ago on Mars there were rivers, lakes and oceans. Temperatures between -125 and 35 C. Violent storms. Moonlike surface, many meteorite craters and vulcanoes. But the inner structure and history of the planet is rather similar to those of the Earth.
