It's interesting how recent studies have shown that a lot of Earth's water came from meteors vs the end result of Earth's formation. Also recent studies show a major asteroid may have hit Earth about 13,000 years ago.
It's interesting how the bible when speaking about the great flood describes it as the floodgates of heaven opening up. If meteors did send the majority of water to Earth, then a water meteor storm would be a good description of the great flood.
