Yes,Other planets could scientists believed some life were on other planets and signs of life
Scientist have been sending rovers and astronauts to the other planets to detect life on other planets. (I think I'm not 100% sure,sorry)
Because they are like other life planets they might be able to produce more life when Earth explodes.
there might well be life but there is no live
Most planets would be too challenging for life at all. So far, just Earth seems to have the necessary ingredients to spawn life. We keep hoping for signs on Mars, but to date, no joy.
Currently there is no space ship that is searching for life on other planets. However, there is an unmanned vehicle (the Curiosity rover) which is currently on Mars looking for signs of life, previous and current.
All life as we currently know it cannot exist without water (H2O). Scientists look for signs of water when searching for life on other planets.
mars
liquid water, the right amount of gases, and the temperature has to have a definite position.
So far most planets are too hot or too cold to support life or are gas giants. Scientists are yet to find signs of life in other planets, other than planet Earth. The universe has many galaxies and planets, most are still yet to be explored. The search for extraterrestrial life is ongoing.
Liquid water is an indicator that there is probably life present.
Life which does not originate from planet Earth may very well have developed on other planets. There is really no other explanation for where it would have come from.
