New minerals began to from because of the intense heat that turned our Earth from being black in color to being gray. 
2.) Earth cooled down and allowed for liquid water to form and turn Earth blue about 4.3 billion years ago. This was proven with the discovery of zircon that was produced only in an environment where liquid water was present. 
3.) Amino Acids were formed with the presents of water, gases, and electricity which then created proteins.
