All patterns in nature (phenomena) require energy to upkeep. Some require a lot of energy, representing complexity. Others require little energy, requiring simplicity. The ideal of a man walking on water and turning water to wine, is a pattern associated with Jesus Christ and Christianity as a whole. People cannot repeat this pattern in reality. Simply demand, at any time, that a person prove to you these claims, and they won’t. But the ideal is significant, because it represents a lot of other phenomena, particular to the moral and ethical structures of Christian societies and peoples. The ideal is symbolic. Its realism is less important. Is religion supposed to be scientific, or vice versa? Is Faith equivalent to Trial? No, Science demands strict requirements of proof and evidence, such that experiments must be repeatable and proven across different environments and centuries apart. Gravity and Natural Law operate the same now, as millennia ago, or millennia into the future.
Regardless, people will invest energy into ideals, superstitions, fantasies, and all other manners of speculations, or opinions even when they’re wrong. This will require an upkeep, that they are willing to pay, because of underlying motivations. Sentimental value, for example, can force a person to retain false opinions or delusions, that are not repeatable in nature, or simply never occurred in nature. The fact that Mankind can spend so much time and energy on false opinions, false ideals, and false representations, is what separates him from other less intelligent and less evolved animals.
Sometimes, a false ideal can be worthwhile, which is a risk. When Nicolaus Copernicus rejected Geocentricism for Heliocentricism, it was a false ideal at the time, but later proved true. But this is the exception, not the rule.
So no matter how much time & energy people want to force into walking on water, and turning water into wine, pragmatically it is more useful to concern themselves with practical matters.
Then again, Humanity now has excess time to waste on trivial and rather meaningless endeavors. This is the plight of Postmodernity.
