We can never be right or wrong on everything we believe.
What we believe is our reality on this planet. We can argue all day long about who is right and who is wrong, but in the end, it doesn't matter, because we all believe in something that is our reality. I try to rely on science to explain our environment, and who we are. It's really about philosophy.
Definition of philosophy of life. 1 :an overall vision of or attitude toward life and the purpose of life. 2. [translation of German Lebensphilosophie] :any of various philosophies that emphasize human life or life in general.
