Your focus determines your reality...
What are metachloreans?
Metachloreans are a microscopic lifeform that resides within all living cells.
They live inside me?!
Inside your cells, yes...and we are symbionts with them.
Lifeforms living together for mutual advantage. Without the metachlorians life could not exist and we would have no knowledge of the force. They continually speak to us, telling us of the will of the force. When you learn to quiet your mind, you'll hear them speaking to you.
from Star Wars, Episode 1, The Phantom Menace
My only comment is that if life could not exist, then why bother worrying about knowledge of the force? Unless, of course, knowledge of the force could exist without life.
