The point of this film is not the science nor the philosophy but really that science IS philosophy. Mankind will never be able to explain all the why's of human existence. When it thinks that it has it will have to contend with the "why" of it all. To me, science deepens the mystery of life. There is no certitude. You don't have to believe their answers only the questions. I would like to refer you the great physicist, Stephen Hawking who said, and I paraphrase what is it that breathes life into the universe? What is it causes the universe to bother in creating itself, whether it is done by its nature or by an external influence? Indeed what is the meaning of life itself. This film doesn't tell you, but it sure entertains you in its attempt to try.
