Very good, man.
How I see it?
Religion and sciense alike are in search of answers that they will probably never be able to answer. Let me explain with a conversation between the two: (Note: I don't think alot of religious persons are pursued so easy.. but just for the point of arguement)
Science: "We are. But why?"
Religion: "God made us"
S: "Why did He make us?"
R: "To glorify Him"
S: "Then what is Hís purpose?"
R: "I do not know, but that is the same problem as you have; you do not know 'why'."
S: "Agreed. Then, by any chance, do you know how God came to be?"
R: "God is, was, and will be. He was not created."
S: "Why? How is that possible?"
R: "I do not know. But yet again, that is your problem as well, is it not? How was man created?"
S: "In other words, we should ask ourselves: 'why is there existance?'"
R: "Is it then not nice to feel like there is a goal to life?"
S: "Not if that goal isn't built around facts, but things that 'could be'. But how is it possible that there is existance in the first place? Logically, we shouldn't exist.
R: "Thus, our existance is preset."
S: "No, because the existance of someone or something to 'preset' us is just as unlogical. And then, what about free will?"
R (can't answer the question, then realises it): "Well .. ehm .. There .. is none?" (reason I don't believe in the bible, but I believe a God or supreme being míght exist)
S: "To be honest, according to consequences, everything is preset in our view as well."
R: "Then there is no reason.."
S: "It's 50/50. Just like every one of these important questions noone can answer is 50/50. How can we exist? Well, how can we not exist. See what I mean with 50/50?"
R: "Yes. But I can tell you this: if not belief than hope shall guide me."
This is the problem with both religion and science. I believe religion was something to make people have a higher goal that would make sure they did not do unethical things. Alass, ethics change, and religion does not.
Science was created to dispute religion, and as greatest weapon it used just the same illusion religion did: an answer to a millenia old question which was not really an answer.
Religion says: "God created us", which sounds like an explanation, and is in truth an illusion of an answer. Because, who created God?
Science says "The big bang/insert random theory created us", but how did the Big Bang/random theory come to be?
Even now that the big bang is (sort of) proven, it still is no question and raises many more, such as: "did God control the big bang?"
I do not believe in free will, but I also think it doesn't matter to us. Wé do not know what will happen, so why should we care that things can't be changed, if we do not know the future and thus present ourself an illusion of free will? Is that so bad? At least it doesn't harm anyone.
If there was no hope, there was no love, no guilt, no nothing. So hope indeed is perhaps the best answer available to us.
Why do humans have feelings and animals don't? Because our brains are so developed that we need hope as a reason, simply because we ask ourselves for it. Animals don't ask 'why', so they don't need feelings.
I liked the movie :). Very weird ending btw.
