Did Mars Have Life Before?

Could Mars have hosted life before Earth even did? Scientists believe ancient Mars was once warm, wet, and full of potential. With evidence of dried-up riverbeds, buried lakes, and even organic molecules found by NASA rovers, the Red Planet may have supported microbial life billions of years ago. Some meteorites from Mars even show strange microscopic structures that resemble fossilized bacteria. While there’s still no direct proof, every discovery brings us closer to answering one of humanity’s biggest questions: Was Mars ever alive?
