Me as well. But there are obvious hints that the roots of religion are involved—the explorers go from being very fact driven to eventually wandering more on faith than anything else. There is also a kind of recursion within the story that suggests larger ideas as well…
But, yeah, we might just have to ruminate on how a work of fiction like this makes us feel.
After seeing a lot of indie films, I've come to find peace with that idea: that not everything in fiction has to be knowable, have a series of events that build to some succinct conclusion.
(And I probably encountered this first even when in elementary school when a teacher finished reading a book and asked us, "What do you think happened to the boy after the story ends?" Initially frustrating to me, I came to accept that perhaps the author is allowing my own imagination to participate as well.)
Sometimes, you wake up from a semi-lucid dream with a feeling unlike any you have had before. An attempt to describe it with words or visually will, if you are lucky, come close to approximating it. Almost surely though the fiction that results will be inscrutable if held to standards of logic or narrative. And that's just the way some things are within the human mind.
