Ah it’s such a huge question that I couldn’t even begin to answer it in a HN comment. I think you’d need to study the collective knowledge of religion and science as background.
Where I would start, though, is by trying to “re-center” humanity in the universe in a way that is logically and scientifically justifiable, against the widespread belief that we’re just lost in space. If you could do that, you’d have a strong step toward making the life of an average person have a kind of cosmic significance that was more prevent in older religious times.
Nietzsche is good reading for this, as I think he correctly diagnoses the issue. His solutions are a bit vague or too personal and not systematic enough though.
