      • Meteorites carried Amino acid witch were attracted to each other then they came together to make protein and amino acid replicated themselves aka copying themselves. They turned into DNA and then made bacteria. Witch then made life

      • The bacteria breathed of a gas oxygen. Every bit of bacteria made a tiny bit of oxygen
