NOTES:

100 billion comets in solar system are chemical factories that produce an array of organic compounds from amino acids to proteins. Despite space radiation and cold temperatures, internal radiation at the core of the comet melts some of the ice into liquid water, facilitating the creation of organize molecules.  Clay is only made with water.

Last common ancestor <3 billions micro organisms 4 billion years ago.

Metors have 4.57 billion year old vesicles the size of cells formed by molecules as cell membranes.

Thermal vent molecules, e.g. iron sulfide catalyze CO2 and H.

Base molecules of DNA/RNA, guynmine, amlymine.

NEW:

Glycine found in comet.
