@CorruptUser It is possible that microbial Earth life has contaminated Venus or Mars via meteroites. The upper atmosphere of Venus 50km up has temperatures and pressures similar to sea level on Earth. Venus is also the only place in the solar system where it is theoretically possible to create a cloud city like Lando Calrissian's, because an object filled with Earth air would float in carbon dioxide like a helium balloon.
