Bible never mentions no neptune dont know where he got that. The water is still here. Google "if the earth were a perfect sphere how deep would the ocean be?" There is enough water for a global flood and ancient civilizations around the world have stories about it.
You have made these false claims before and I will call you out every time you post this foolishness. The local and regional floods associated with other ancient cultres have been documented as catastrophic river floods, and tsunamis by archaeological, geological, and records of the ancient cultures. There are other local and regional floods that are documented as associated by glacial floods, and not recorded by ancient cultures.
