Go back a few billion years to the beginning of life on earth, and we run into many possible ideas for how it could have happened. The truth is we just don’t know, but we’ve got a lot of different hypotheses that may or may not explain our weird world. Kurzgesagt explores one idea, a concept that could explain how the earliest life forms on earth were already so evolved that they could live and thrive and evolve here. There is some math involved, but nothing you have to calculate yourself. Along the way, we learn about the conditions of the early universe, and the possibility that life elsewhere might not really be so alien to us. It might not be the right answer, but it does give us a lot to think about, mainly what a miracle our world -and universe- really is. The last couple of minutes of this video is an ad.
