It has been an interesting week in the search for life in our solar system, some news has been good and some disappointing. SciShow discusses the latest information about amino acids in our solar system and the search for methane on Mars.
I hope you're not talking about when proteins are digested in the human body. Because, really, humans are also present in our solar system.
I like the video in general.
