Causality.

What we have here is forgetfulness. Forgetfulness that the origin of self is self not wanting to be by itself and that the purpose of self (and thus the meaning of life) is simply companionship otherwise known as love. This forgetfulness is of course not all that unusual considering the fact that the age of the universe* is 13.787±0.020 billion years. I mean... I barely remember what I did yesterday. As such the purpose of science. The purpose of science is to piece everything together in a simple theory of everything; a theory of everything that was never even elusive to begin with. It simply has always been about love right from the start. (*self)
