Nearly everything in the Bible has a scientific explanation - from the creation to the Red Sea parting to many of the New Testament miracles. However, it's the timing, the way it happened at just the time to suit our needs, and all the little miracles that still happen today. Miracles don't have to be impossible be extraordinary and inspire us. The way the earth and everything on it snaps together so perfectly - yes, it has a scientific explanation, but it was God that guided and maintains that science with his loving hand to help form the world we know and love today. Ya know, there's a reason why we evolved into intelligent human beings rather than just another "dumb" or lacking in intelligence, beast.
Growing up in a Christian church, I have heard many stories about the miracles of God. From the creation of the universe to Noah's Ark they were considered mystical and amazing. But we also taught God as a God of logic as listed in the Bible. Therefore, it would make sense, even from a religious perspective that there would be a scientific explanation for such miracles as the parting of the Red Sea.
Scientists and historians say we can learn about the past from the present. If there is an actual parting of the East China Sea, then there is a scientific explanation for the parting of the Sea in the Bible. Where it sounds unusual in the Bible, this scientific phenomenon in the East China Sea provides evidence that a parting of the sea can happen.
The question is flawed and leading. There may be a scientific explanation for the Biblical parting of the Red Sea, but what does this have to do with the East China sea? In modern society, we seem bent on finding a scientific explanation for everything that seems paranormal. Modern examples of similar phenomena do not explain why no one has seen the Red Sea part since the time of Moses, nor does it explain how the one occurrence happened at just the right moment.
Yes, it's possible that there is a scientific explanation for parting the Sea in the Bible, because there have been a number of different scientific occurrences over the years that could have explained something like that. In addition to the East China Sea, there's the possibility that a strong wind caused the parting. There are many options.
