... God's opinion is still an opinion, and the prophets of God are only expressing their opinions too; they're just claiming more authority than they… - Aron Ra

If there really was one true god, it should be a singular composite of every religion’s gods, an uber-galactic super-genius, and the ultimate entity of the entire cosmos. If a being of that magnitude ever wrote a book, then there would only be one such document; one book of God. It would be dominant everywhere in the world with no predecessors or parallels or alternatives in any language, because mere human authors couldn’t possibly compete with it. And you wouldn’t need faith to believe it, because it would be consistent with all evidence and demonstrably true, revealing profound morality and wisdom far beyond contemporary human capacity. It would invariably inspire a unity of common belief for every reader. If God wrote it, we could expect no less. But what we see instead is the very opposite of that. Instead of only one religion leading to one ultimate truth, we have many different religions with no common origin, all constantly sharding into ever more deeply-divided denominations, seeking conflicting truths, and each somehow claiming divine guidance despite their ongoing divergence in every direction.

There is no such thing as a religious theory, just like science doesn’t promote “non-religious doctrines” either. A doctrine is a set of taught beliefs. Science is an investigation; not a matter of belief.

It just seems to me that we either have an irrational need to believe or we have a desire to understand and to improve that understanding. For those of the latter set, accuracy and accountability are paramount, but for creationists, those things don’t even matter.
