So far, no signs of life have been found on other planets. The best that scientists can do is speculate on whether it does or has existed, based on conditions and estimated conditions of other planets and exoplanets. There is a good chance that other planets around other stars (exoplanets) can support some kind of life, if the conditions are right.
