I agree with that. But we humans cannot help formulating hypotheses to explain life and its purpose.
Not every notion is an hypothesis, though - in order to be an hypothesis the idea needs to be experimentally verifiable. Claims of 'non-physical', 'spiritual' or 'mystic' influences without measurable impacts on reality are not hypotheses; they aren't definitively wrong, but in the absence of a means by which they can be verified or refuted they are something other than hypotheses.
Scientists may keep saying that there need not be any answers to our philosophical questions...but that is neither here nor there.
It is quite an important point - any time you presume that there is something there to be found you are begging the question.
Or alternatively again, we can adopt a Hindu view which also happens to be secular and is not specifically religion based. Existence of a universal Consciousness that is the source of creation. Life is illusionary (maya) like in a VR game. Spiritual evolution of life from lower forms of consciousness to higher forms of consciousness. Soul (atma), after-life, Karma, reincarnation, spiritual progress life after life to eventual freedom. An ongoing process like the water cycle.
'Universal consciousness', 'source of creation', 'higher forms of consciousness', 'soul/atma', 'afterlife', 'Karma', 'reincarnation', 'spiritual progress' - a precise definition of religion is difficult to nail down, but wherever the exact line in the sand is this stuff is from way, way, way over the other side of that line from the materialist viewpoint.
First idea is a default one based purely on sensory inputs. Second is a belief based on scripture. The third is speculative but has some evidence in the form of NDE's, reincarnation research by Jim Tucker etc. Philosophies such as Cosmopsychism and panpsychism support this view.
I'd argue - playing Devil's advocate - that the claim of the religious would be that scripture is the way the message is conveyed, but the original authors were passing on their own sensory inputs. I wouldn't agree with them, but the scripture didn't emerge out of nothing, it was written by people who may have genuinely thought they'd been told about people experiencing exactly what they've recorded.
As to the third, it's just a variant of the second; you've got claims from olden days passed down and unverifiable by actual investigation. Either there is no evidence or the evidence is weak and can be interpreted to support multiple interpretations. Philosophies like panpsychism do not 'support' a view, they ARE the view - they are at best not contradicted by the evidence, but there is no basis for presuming them to have any validity.
Take your pick...
I'll take the phenomena I can establish with some confidence actually exist.
