Yes, they are all amazingly valuable.
Dreadnought,
That's very true. As methods of social control religion has been part of man's cultural tool kit since... well... since man evolved.
Religions are human constructs, nothing more. They exist because humans have had, do have, and will have a need for them. There were uncounted religions before the few Abrahamic versions evolved, there are many non-Abrahamic religions today, and we've seen new religions evolve since.
The Abrahamic versions conceit that their view is the one "true' or "only" view is nothing exactly new. Other religions have claimed that before and others will claim it in the future. The extremes that Abrahamic versions go to to "ensure" or "prove" that their views are correct are nothing exactly new either, we're just more familiar with the consequences of those actions.
If this board were hosted in India and had a majority Hindu membership, the claims and defenses routinely posted our more vocal Christians would seem very odd and very out of place within that Hindu-majority board's "cultural consensus" just as a Hindu religious viewpoint would seem very odd and very out of place on this Abrahamic-majority board.
All religions have always claimed to know the "truth" or significant portions of it. All religions will always claim to know the "truth" or significant portions of it. Boasting that your particular version in this time and place is somehow more "correct" than that of a 2nd Century CE follower of Mithra, a 3rd Century BCE follower of Zoroaster, or a modern day follower Hinduism, Shintoism, or the thousands of other existing religions is both laughable and sad.
Humanity's beliefs have always been and will always be much more varied than the narrow range of options "allowed" within the Abrahamic mindset.
Please pray in whichever way you wish and please don't attempt to tell me your beliefs are logical.
