that’s a very deep question, and one philosophers have been debating for many many years.
It depends on your stand point – I believe that we were created out of the primordial soup that came to be all the way back in the early days of the solar system. The creatures from this soup then evolved, and eventually became what we are today 🙂
Great answer, Aimee! Carl Sagan is definitely one of my science heroes!
What happened in the very beginning, we don’t really know. Where the first spark of life came from is still a total mystery, but what happened afterwards? Well (just like the Pearl Jam song) “It’s evolution, baby!”
This is a good question. We basically all started from some basic amino acids and proteins that, by chance, managed to combine together to make more complex molecules that could reproduce each other. That led the way to single-cell organisms that eventually got together into multi-cell organisms. It all took many millions of years of evolution.
