Will Smith narrates. Astronauts help tell the story from their perspective. They talk about how unique it is, how things had to be just right for life to happen as it is, etc. It's beautifully done.

This is really good. Something flat earthers and creationists should watch, but they won't.

I hope you enjoy the rest of it. I'm going to watch it again. Can't do much about the ones who choose to ignore science.
