There are many modes of thinking about the world around us and our place in it. I like to consider all the angles from which we might gain perspective on our amazing universe and the nature of existence.

Know that the difficulties which lead to confusion in the question what is the purpose of the Universe or of any of its parts, arise from two causes: first, man has an erroneous idea of himself, and believes that the whole world exists only for his sake; secondly, he is ignorant both about the nature of the sublunary world, and about the Creator's intention to give existence to all beings whose existence is possible, because existence is undoubtedly good.
Maimonides
Our comforting sense of the permanence of our natural world, our confidence that it will change gradually and imperceptibly if at all, is the result of a subtly warped perspective. Changes that can affect us can happen in our lifetime in our world--not just changes like wars but bigger and more sweeping events. I believe that without recognizing it we have already stepped over the threshold of such a change; that we are at the end of nature. By the end of nature I do not mean the end of the world. The rain will still fall and the sun shine, though differently than before. When I say 'nature,' I mean a certain set of human ideas about the world and our place in it.
Bill McKibben
I tell you that if natural bodies have it from Nature to be moved by any movement, this can only be circular motion, nor is it possible that Nature has given to any of its integral bodies a propensity to be moved by straight motion. I have many confirmations of this proposition, but for the present one alone suffices, which is this. I suppose the parts of the universe to be in the best arrangement, so that none is out of its place, which is to say that Nature and God have perfectly arranged their structure. This being so, it is impossible for those parts to have it from Nature to be moved in straight, or in other than circular motion, because what moves straight changes place, and if it changes place naturally, then it was at first in a place preternatural to it, which goes against the supposition. Therefore, if the parts of the world are well ordered, straight motion is superfluous and not natural, and they can only have it when some body is forcibly removed from its natural place, to which it would then return by a straight line, for thus it appears that a part of the earth does [move] when separated from its whole. I said "it appears to us," because I am not against thinking that not even for such an effect does Nature make use of straight line motion.
Galileo Galilei
The progress of science requires more than new data; it needs novel frameworks and contexts. And where do these fundamentally new views of the world arise? They are not simply discovered by pure observation; they require new modes of thought. And where can we find them, if old modes do not even include the right metaphors? The nature of true genius must lie in the elusive capacity to construct these new modes from apparent darkness. The basic chanciness and unpredictability of science must also reside in the inherent difficulty of such a task.
Stephen Jay Gould
"The universe does not owe you a sense of hope. It could be that the world, the universe, is a totally hopeless place. I don't as a matter of fact think it is, but even if it were - that would not be a good reason for believing in God. You cannot say "I believe in X", whatever X is - God or anything else - "because that gives me hope". You have to say "I believe in X because there is some evidence for X". In the case of God - there is not a tiny shred of evidence for the existence of any kind of god.” ... “There's plenty of reason for hope in a Godless world. The universe is a beautiful place. The world is a beautiful place. To understand it in a clear-eyed, open-eyed way; to look out at the world and to really understand why we exist, what it's all about - that is a hugely uplifting feeling; That really does give a sense of worth to life, even if life itself is finite, as I believe it is. Nevertheless, it is not a hopeless life without a god, and to re-divert to my earlier point, even if it were - then it's just illogical to say that that gives you evidence for the belief in God."
