The disks of gas, dust and debris observed with modern infrared and millimetre-wave instruments in nearby star systems are considered to act as locators to large colliding bodies. These observations are problematic for the evolutionary nebula theory of the formation of planetary systems, but can be easily interpreted from a biblical creationist worldview. By that I mean they provide evidence consistent with a Young Solar System creation scenario as described in Genesis 1.
My proposal is that these cratering bodies are analogues for the ‘waters above’, mentioned in the initial creation of the world (Genesis 1:7), which in part were used by God during the Curse and the Flood. Under this hypothesis, the ‘waters above’ would represent all the bodies, large and small, that lay beyond Neptune in our solar system, including all the cometary material, mostly made of water ice.
