Why do you exist? According to the Anthropic Principle, it might just be because the universe wants you to. Theorized in 1957, it essentially states that because the universe can be observed and interacted with at all, that complex life is naturally destined and selected to observe and interact with it to begin with. It's almost like the saying of the tree falling in the forest. If known observes it, it might as well not exist, but because it can be and is observed, does. Now conscious thought and observation isn't the prerequisite for basic physics to form stars and develop life, but the theory does entice the imagination. And if true, the universe might just want you to exist, fall just in the loop.
