Studies in Genesis 1
And God made the expanse and separated the waters that were under the expanse from the waters that were above the expanse. And it was so. (Genesis 1:7 ESV)
Here are some elementary earth science observations.
As God formed earth He made water a necessity for life. Water is made up of two hydrogen atoms and one oxygen atom bonded together. Hydrogen and oxygen exist independently yet come together, as a law of nature, to form water.
There is just as much hydrogen and oxygen atoms now as there were in the beginning of creation. Because we live in a closed system called the universe matter cannot be introduced or extracted. There is just as much matter now as there was however long ago the universe began.
Most of the physical composition of every living thing on our planet is water. God instituted a law governing the amount of water contained in every living thing. Too much or too little and the living thing dies.
God set in place a system for cycling water throughout the planet. Water covers most of the surface helping keep the planet at a constant temperature. Water evaporates from the oceans into the atmosphere helping protect the planet from the harmful effects of radiation from the sun. Evaporated water condenses and waters the surface of the planet so life continues to live.
Some have suggested these laws are naturally occurring. Others, me included, suggest the involvement of intelligence in the design of nature. Both conclusions are certainly possible. But which conclusion is reasonable? We will continue to examine the evidence.
