One thing that attracts people are miracles. The notion is simple, what we cannot perceive through our senses or cannot understand through our limited experiences we consider that a miracle. Say someone can levitate, then through our experiences and senses we know that is not possible, so then the logical mind (Buddhi) says it either a trick or a miracle. But if we can understand the underlying mechanisms of it, then we may begin to accept it. Planes are one such example they fly like birds in the sky, just over a century ago this might have been considered a miracle, since something heavier than air cannot fly.
Miracles exisit in nature, how can a cow eat grass and produce milk that is so high in calcium? There are many such examples in nature, only if we care to look. In science seeing is believing, in spirituality believing will lead to seeing (truth)
