Ok I am going to proceed with lot of care and respect as this discussion may involve respected religious figures.
There are hundreds of events that are described in religious scriptures that defy norms, hence called miracles (or such).
I mean, today if a virgin gives birth, it can easily be explained, as artificial insemination is a very known phenomenon.
Split of moon maybe hard to explain, but you can theoretically see moon (half moon in this case) on one side of the sky and its mirror image on the other side if a ‘strong gravitational lens’ is present in the vicinity. (Gravitational lens is the phenomenon that bends the light in such a way, that an image of a heavenly body reaches us through two light beams, giving us the impression that we are seeing the same object at two different locations of the sky).
What other miracles/not-so-normal stories that you remember from Quran, Bible or other books, that can now be (at least theoretically) explained, using Science.
I give you one challenge. Explain the little pebbles that turned Abraha;s elephants into dust when birds dropped them on the elephants. (Sura e Feel). Are such tiny bombs possible?
