I am a huge believer in both existentialism as well as absurdism.
Life has no overall meaning or purpose besides the meaning that we give to our own lives. Everything, however, is ultimately meaningless, religion is a joke and our vague understanding of the universe will never give us the answers that we seek. Eventually the tiny green planet will die with everyone on it, the earth will be consumed by the sun and mankind will never be heard of again, POOF! This may be depression and is truly no way to live a life but in an odd way, it gives me comfort knowing that there is no point in trying to search for a "higher meaning or god" because no one has yet found it, it allows me to focus on other things in life that have more purpose to me personally. I no longer have to think about the big picture because there is none, all that matters is mankind and my mind.
