Thoughts create life, processes.  We are acting out a process from the mind of a being like neurons firing to deliver an answer.  Nearly every human considers at one point, what is the meaning of life?  Well, there is an answer, but we will have to keep searching.  Whatever being discovers it, when it is discovered, the world will end, because the process will have fulfilled it's goal.  It is possible that humans are not meant to find it, but some later evolution. 

"..when you think, remember or feel, the process...in your head is...evolution.."
