What comes first goo or machine?

What comes first? Does a life form technically advance far enough to create the magic green goo to be used for good or evil? Or did the universe create the goo through its own evolution and found and used by an intelligent steward? Seems like this movie will focus on the classic sci fi theme of the android desiring to be more human like there by trying to acquire and use the green goo to merge life and machine together.
