  It was probably by accident. A couple of proteins came together and eventually they could reproduce. Over time these cells became more and more complex as they adapted to their conditions so that eventually multi-cellular organisms began appearing and then animals. That’s just a guess though.

  This question is one many people have spent a lot of time trying to answer and many theories exist. The study and theory of how early life could have started on Earth is called Abiogenesis. The truth is no one really knows how life began exactly. And I’m only talking as a scientist; many chose to believe that a God of some kind (depending on their religion) created life.
  
  My personal view is that the first living things on Earth were be single cell prokaryotes, which are a type of cell without a nucleus and that over time evolution played a part in these cells becoming more specialised and coming together as larger organisms that eventually created the living things we know today, maybe including us humans!

  Gradually over millions of years, though exactly how nobody knows
