Although miracles happen in the Bible, their use seems to be minimized. Not sinking while walking across the lake is certainly unusual, but slogging across the lake in a storm by foot is not making things easier for Himself. Many miracles likely have more of a natural explanation than popular imagination holds. For example, Exodus mentions the wind that was used to part the water. Wave calculations support the possibility that just the right wind would have set up a seiche, parting one of the Bitter Lakes. But it’s not as if this happened every afternoon at five on Egypt’s border and the Egyptians never noticed - there’s some impressive coordination of timing involved.
Walking on water itself does not have a plausible natural explanation. There was a study showing that the underwater springs in the Sea of Galilee produce patches of water with different salinity and thus different freezing points. As a result, one could have small patches of ice on an otherwise unfrozen lake. So far, so good. But the idea that Jesus was standing on such an ice patch to apparently walk on water does not reflect serious consideration of the practicality. Besides the very low likelihood that He was a champion surfer, even champion surfers do not use blocks of ice for surfboards. This is during a storm, which would interfere both with having stable patches of water of differing salinity and with the ability to balance on a melting bit of ice. Similarly, the suggestion that Elijah actually dumped kerosene, not water, over his sacrifice fails to explain Elijah’s miraculous ability to refine hydrocarbons well before the procedure was invented.
