"Back To The Cave" by Joe Diffie is a humorous song that explores the idea that no matter how much we advance technologically, we are still driven by the same primal desires that our early human ancestors had. The song starts with a scene from the dawn of man where a man and a woman find attraction in each other but cannot express it in words. They resort to primitive gestures to ask if they want to go back to the cave and make a fire, which implies that they want to have sex. The song then jumps to a modern-day Texas bar where a cowboy meets a woman named Irene. He is charmed by her and tries to impress her, but ultimately suggests going back to the cave. The chorus repeats the idea that the desire for sex is innate and goes back to the very beginning of human history. The song later references the Flintstones and suggests that we can be like them and embrace our primal desires. The lyrics "Don't blame us for the way we behave, The only way we know, goes back to the cave" emphasize that humans have always been driven by these desires and it's a part of our nature. The song is light-hearted and humorous but also raises the idea that as advanced as we may be, we are still essentially animals with certain basic desires.
