The surface of Gaus would cool and crack as the surface cooled and solidified in a thin crust and then unexpectedly burst open in areas spewing molten rock, ash, and gas. All the water on Gaus was still in a gaseous form as it was still too hot for liquid water to exist on the surface. It would be ages and ages but the passing of time was not relevant to anything on the planet Gaus since there was nothing yet living on the planet’s surface. It was the elements that would play out their lifeless battles against each other witnessed by no one.
At last the planet gradually cooled so that the clouds above would evolve into fluffy castles in the sky and the first drops of precipitation would start falling. However, the surface refused to yield and the drops turned back into steam upon hitting the surface. At this time, the volcanoes still roared spewing their contents but at least now the surface was more stable and not heaving to and fro as it was earlier.
Ages continued to pass and the surface cooled even further. It was during this time that all the water which had been forced to remain as a gas previously was now able to condense into little pools and streams upon hitting the surface without turning back into steam. There were storms at this time, storms of such magnitude that had never been witnessed by humankind as the cooling of the atmosphere forced it to give up its water. The pools and rivulets of water grew flowing over rock and ash dissolving minerals and coagulating into an ever increasing number of ponds and lakes. The growing streams and fast moving rivers continued carrying their cargo to their final destination as the numerous early lakes and ponds began merging together.
As the planet continued cooling, these primordial bodies of water continued to coagulate and expand into seas covering hundreds of square miles. Planet Gaus at this time had cooled enough setting the stage for life.
