It was the Red Sea he split. He led the slaves out of Egypt, and split the Red Sea to escape into what we now call Saudi Arabia. Splitting the Nile wouldnt actually allow them to escape the Egyptians, as the level of water in the Nile wouldn't have been high enough to wash the Egyptians away like they were in the story, which means they would have been caught again.
