The first life forms on Earth were likely single-celled organisms such as bacteria or archaea that appeared around 3.5 to 4 billion years ago. These simple organisms were the precursors to all life that followed.
Well, right now nobody's completely sure exactly what the first organism is. But we do know that the first organisms on earth were microorganisms (germs), which all eventually started evolving into multicellular organisms and got more diverse.
Chemoautotrophs were the first life on this earth. Chemoautotrophs were small living organisms that were considered to be simple cells.
The first living thing that came to earth was Apes to convert to dinosaurs and so on, so forth...
