You cant just assume that because reality needs a reason to be, otherwise it wouldn't, that automatically manmade religions are true. because their is nothing to back such an assumption up, it is a guess based on nothing but human writings and stories. the fact that those writings will always have the possibility of being false as long as no gods show up, or an event occurs that proves them undeniably true, makes it meaningless to choose a religion as the answer to the mystery of being. religion is for people who are too weak to go on without support in their lives, and people too afraid to stare the truth in the eye, which is that the truth about existence is unknown.
