The human mind, with its recursive combinatorial power, can explore an infinite space of ideas, and is not limited by the quantity of any particular kind of stuff in the ground. When one idea no longer works, another can take its place. This doesn't defy the laws of probability but obeys them. Why should the laws of nature have allowed exactly one physically possible way of satisfying a human desire, no more and no less?
