How to make sand.

The Biblical literal model would be that the planet was, at the time God's spirit began to do the work on it, had a cold watery surface in which the water was mixed in the soil and the rock. The consistence of the surface is not known, as to rock/soil/sand, etc. For an unknown period of time before the work was to commence the planet existed, including a large quantity of water, either in the atmosphere or on the surface. There was no sun so the mixture was likely frozen.How much volcanic activity before the work on the earth surface and after is unknown.The Biblical model leaves questions but does address the unique phenomena of the quantity water that we observer on our planet as opposed to other bodies studied. I'm not sure what the conventional model for the earth's water is, but then that is a different topic. Likely the water factored in creating the earth's sands.The Buzsaw model does not determine the length of days of one through four, in that there would be no sun to determine the 24 hour day until some time in day four.I've said the above to say that there could have been a very long period of time before and during the Genesis work for sand to have been formed.Once God, via his spirit's heat and light caused the atmosphere to form, the oceans, which would have been relatively shallow likely caused sand to be made by waves, erosion and whatever, somewhat like the conventional model.Bottom line, Earth's sand was likely made fairly consistent with the conventional model in the process of creation. The amount of heat, light, water, etc would have been managed the ID of God so as to accomplish the desired goal in preparation for the plants, animals and mankind.
