The answer to the question - is the universe a quantum fluctuation - is, abstractly speaking, yes. However. Truth is simpler. The universe is self. Self is singular. Singular as in one. One not wanting to be alone. Now. To return to the opening question. What is the relationship between quantum fluctuations, the big bang and the theory of evolution. Truth is very simple. The origin of self is self not wanting to be by itself. As such self fluctuates itself. Self fluctuates itself so to not to be by itself.  Self fluctuates itself so to be able to to experience companionship. Companionship being a synonym for friendship. Friendship being a synonym for love. AmitiΓ©? Yes. Love self is. Self is love in action. Very true. Truly simple. One love.
