Why does the universe exist? Everyone has heard theories about how our universe appeared. The most popular theory in the scientific community is Big Bang Theory. However, all the theories answer the question "how", but not "why". There are billions of lifeless planets in the space. Why do all of them exist? What is the purpose of lifeless planets that humans will never reach? The problem here is the "why" question. When we ask "why", we refer to motivation and intentions of a person. The question "why did he do that?" means "what was his motivation to do that?", "what reasons did he have to do that?". However, if we ask a "why" question about an inanimate object, it is a completely different question. "Why did tsunami happen?" actually means "How did tsunami happen?", cause tsunami has no motivation or intentions. When we ask "why", we ask about the process and how it proceeds. So what is the answer to the question "why does the universe exist?". This question simply doesn't make sense. We can ask "how does it exist?", "what processes occur in the universe?", "how has it appeared?", but the universe has no motivation or reasons to exist.
