Have you ever wondered how we came about? Or maybe how those fancy scientists know so much about evolution! I mean … It’s just a theory, right? Well, David Christian is here to tell you that when scientists use the word theory, it holds a bit more weight than when we say it. More than that, this guy provides a great explanation on the origins of our planet and universe. He explains everything well enough that anyone can understand, and has enough scientific proof to sink the room. Have fun!
