The article explores the hypothesis that life on Earth may have originated from microorganisms on Mars, which could have been transported via meteorites. It discusses the timing of planetary formation, early conditions on Mars and Earth, and the challenges of microbial survival during space travel, ultimately questioning whether Earth’s life could have come from Mars or if it originated independently on Earth.
