Answer 2

things that want to move and are formed in layers arent really alive ,., you cant hide becuase you want to be a god too!

Answer 3

The answer would be bacteria and archea. Where ever there is water live will thrive. Bacteria and archea can live in many extreme conditions. Bacteria called thermophiles can live in in conditions of upwards of 100C and subject there selves to 300 atmospheres of pressure. Bacteria can also live in low to no oxygen environments like you may find in the upper atmosphere. Some scientist also believe that there may be life on Venus. The upper atmosphere of Venus has water vapor and temperatures of around 50C. Back to your question the answer is bacteria and archea.
