In Genesis 1:6–8 the Bible reveals to us that, on Day 2 of Creation, God made an expanse, called "Heaven" and separated the waters below the expanse from the waters above it. The nature and location of these "waters above" have been debated for some time. Further complicating the puzzle, the Bible speaks of three heavens. The first step is to define these "heavens." Then we might know where the waters were located. Three models will be compared—the Vapor Canopy Model, the White Hole Theory model, and the Hartnett-Carmeli model. Each one locates the waters above differently—above the atmosphere, around the universe, and around the outer reaches of the solar system respectively. The strengths and weaknesses of each are compared in an attempt to come closer to the truth.
