When I say difficult questions, I mean questions that we'll most likely never known the answer to, questions like "Is there a god, or higher being?", " What's the true purpose of the universe?", "How did the universe begin, if there was nothing before the universe?" and once you ask yourself questions like those, you start asking yourself more questions like "If there is a god, why does he let us suffer and feel pain?", "If the purpose of the universe is to have life, why did it take so long for life to finally to appear?". I ask myself these questions all the time trying to seek an answer, to get a better understanding of life, because it's so complex. I'm a critical thinker, I never stop thinking, these are the questions that drive me insane. I'm curious, do you ever ask yourself questions like these? And what's your answer to them?
