There is some truth in all religions. But that truth usually consists of common sense wisdom and facts about human psychology that people have acquired over the centuries. One certainly doesn't need religion to learn those truths, and those truths didn't originate with religion but was adopted by them - the same are morality.
The other more extraordinary claims of religions are almost certainly all false. One of the common tactics religions use is to give themselves credibility by demonstrating the truthfulness of their more trivial common sense claims and claims about human psychology, and then ride that wave or credibility to persuade people to accept their more ridiculous extraordinary claims.
For example, a religious authority might say something like: 'Modern psychologists have proven that the bible is right when it says 'an answer when mild turns away rage'. This proves it's a book of truth and wisdom inspired by God. Therefore we must not doubt it's truthfulness when it says that God made the first woman from a rib of the first man!'.
