I understand why people have religions. They want to know about their situation. They want to understand what it's all about. They know intuitively that there's more to reality than what their senses suggest.
Religions are an example of that drive. Religions utilize the tool of narrative; it is a powerful means of remembering, understanding, and fabricating. But most religions are not very imaginative; they borrow heavily from one another, and they default to the authoritarian and hierarchy. They work tolerably well in that their rigidity that does not allow their adherents to question their dogma. Thereby, they give their believers a certain security and structure. But their 'teachings' are vague. We do not know which parts of them ought to be taken literally, and which parts are not. And people of one religion susceptible to feel threatened by other religions, or questioning systems such as Science.
Science used to be quite useful in a global sort of sense. It did or does fall down a little in terms of it core belief in understanding the whole by breaking it up into its component bits. But over time it has become to large and unwieldy. One cannot easily to attain a good general scientific education.
There's logic, which works well in certain realms.
There's experience.
There's philosophy.
But overall I'm going to run with my Sliver Theory.
