      the first species wasn’t bought to this planet according to Darwin’s theory of evolution. it was probably a cell that learned to make energy from the sunlight and then other cells evolved to work together with each other so they could get more energy and grow and life very slowly evolved… but we’re not certain

      Agreeing with Arthur, but would just add that another theory is that some basic cells live on comets & perhaps got transferred to earth that way. That’s one of the reasons scientists wanted to land on a comet! To see if there’s life on one! 🙂

      Water is thought to possibly have come from comets too…
