Of course not all of these.
Is there planets with life. Among the 24 superhabitable candidates astronomers say they identified 9 orbiting around k stars 16 planets between 5 and 8 billion years old deemed the sweet spot for complex life and 5 planets in the optimal temperature range for a superhabitable planet roughly 19 c. The prevalence of life in the galaxy and how lucky we get as we take those first tentative exploratory steps. The new calculations suggest that there are at least four livable planets at a relatively close distance from earth between 20 and 30 light years away an inconceivable number for a human sure.
Is there life on other planets. In september 2020 astronomers identified 24 potential superhabitable planets planets better than earth including unconfirmed planets from among more than 4000 confirmed exoplanets at present based on astrophysical parameters as well as the natural history of known life forms on the earth. Conservative estimates assert that the observable universe may contain as many as 5 300 000 000 000 habitable worlds that s 5 3 trillion planets that might contain life.
For instance nearly three centuries ago the famous hymn writer isaac watts opined that other planets in the solar system were inhabited when he said several of the planets. Some people believed that there was life on the moon and even on the sun. How soon that can happen depends on two unknowns.
