"Hey! It's a Happy Day!"[1] A narrator notes: "Today we relate the life of L. Ron Hubbard: Teacher, author, explorer, atomic physicist, nautical engineer, choreographer, horticulturist, and father of Scientology!"[23] Hubbard is born in a nativity scene, surrounded by parents and barnyard animals, as an angel proclaims, "Billions of years of evolution had climaxed with his birth."[2][15] He begins to question the nature of his existence. He is adrift on a boat in the Pacific Ocean during his service in World War II, when he begins to think about starting a religion.[15] Hubbard tells his followers about what he has learned through his travels in "Science of the Mind", singing about "the key to being free, the way to be happy".[23] He tells his followers that during the War "I saw how emotion can make you blind", and he begins to teach his followers about the reactive mind.[23]
