Orgin of life

I think life started from people being born and than every year the people that were 1st born start realizing how life works and they just kept explaining to the next group of people. The human race just kept evolving from half humans in to full human form. How and why that happened has all come down to the earth changing and how all life started. I think the meaning of life is that every organism is born and you live out what ever you are in. Some people say when you die you could come back something else. But that theory is completely unknown.life is all controlled by a couple amount of acids and things we need As evolution keeps moving on the changes of life will be so greatly different.

1.The ideas are connected because i already knew that there are things that all living organisms need. I did not know that it was a 20 set of amino acids that make up entire life through.

2.well the question how did earth know what these amino acids work to live life? Its cool to think about, that there are a group of amino acids things that all living organisms need to survive. Really cool how they are looking at things from space that have these amino acids and etc. that could of created the earth and life. Unfortunately most of that evidence is not on earth.

3.the thought that if there is one change in these amino acids can change everything and the overall being of that organism is scary to think about. My question still remains how is it that there is a specific set of things all living things need when all we do is live are life not thinking about that? Because i have never even really thought about life before. I mean I've just thought about how did life start where are we right now? Is life just you live and than you die?

I think its so intresting how sceintist make there entire life on studying just one thing. I think the fact that everyone should know how life was created and how we live from these things that we dont even know are
