As for the word "heavens," this is derived from the Hebrew word שָׁמַיִם (shamayim). According to Gesenius' Hebrew Lexicon, this word refers to the sky or visible heavens, including the stars and galaxies. In other words, Genesis is a discussion of the creation and purpose of the physical universe.
This verse also solves the riddle of what scientists refer to as the singularity problem.
The singularity problem, quite simply, is the notion that scientists cannot figure out what existed prior to the theoretical initial blast of creation now termed the big bang.
The big bang theory has been theoretically scientifically validated by one primary observation: That the collection of various galaxies and their components appear to be expanding outward into space. This is called the "Hubble Constant," named after the famed astronomer.
The logic is that if the galaxies and their components are all expanding, they must have originally arose from a single point. For the virtue of science, let's elaborate on this theory for a bit.
Assuming such a single big bang did occur, what made it occur?
In any explosion - or any event for that matter - the laws of the physical universe tell us that there must exist the elements to produce that event. In other words, every event - and every thing in the physical universe - has a source. This we have learned by scientific observation and many decades of research.
Science, as promulgated by scientists now and in the past, must abide by certain laws of logic, one being that scientific theories, no matter how abstract, must abide by fundamental and observable realities.
Therefore, for the supposed big bang theory to be a scientific theory, it must abide by the universal rule of the physical world that every event must have an elementary source.
For this reason, scientists have been meticulously listing the atomic elements that must have existed prior to the big bang in order for the explosion to have taken place.
But then they arrive at the singularity problem: Where did these elements come from? And where did the atomic energy come from that caused such a great explosion?
This is what baffles scientists, and what has provided the grist for many a theory about what existed prior to the big bang. Theories have ranged from string theories to various wave and energy theories, to the famous "theory of everything."
However, at the end of all of these theories, scientists find the same problem: What caused these? What elements, power or energy produced them?
Furthermore, as we look at the eventual assembly of the various beautifully organized structures of the physical universe, be they galaxies, solar systems, planets, oceans, mountains, plants, fish, animals and humans - and their continued evolution driven by a magnificent spiral-shape molecule that looks strikingly like a galaxy, called DNA - we must arrive at the conclusion that whatever was before such a creation event must also have had the potential to produce all of this arranged complexity.
In addition, we must also scientifically accept that all of the personalities among the organisms we see around us - every human and every animal and other living organism - must also have arisen from something. What was the source of all of these personalities? What is the source of love? What is the source of individuality? What is the source of desire? What is the source of the fear of death? Certainly, if we were all simply physical machines, there would be no fear of death. We would all look forward to merging back into matter as opposed to struggling for survival.
All of these elements, which all came into being, add to the singularity problem. Where did the capability for matter to produce all of this come from? The big bang theorists simply have no logical explanation.
This first verse in Genesis provides the answer. God - the Original Being from a dimension of another substance - the spiritual dimension - brought the energy and the elements together to produce the physical universe.
This is the only valid scientific conclusion that can be made. Why? Because first of all, the only valid source of the 'singularity' must be from another dimension. Since "something" cannot come from "nothing," and a beginning indicates a period of "nothing," the only valid source of the "something" must be a transmutation from another dimension.
Secondly, in order for the physical universe to have the capabilities it has: such as spiraling galaxies, gravity, DNA, atoms, molecules and so on, there must be an organizing source. Something must have provided an organizing principle.
An organizing principle requires what? Purpose: A purpose for the organization. Something that is organized infers there is a purpose for the organization. This requires an organizer with purpose.
Thirdly, life must originate from a living substance. Matter cannot become life. We can see this clearly. A living organism desires survival. A dead piece of matter does not. This means there is a difference between the two. So how did life come into being? Since living organisms struggle against the laws of the physical universe - notably that every organism dies - then the life element within living organisms must not be physical. If they were, then there would be no struggle with death. Every organism would happily accept death as a merging back to matter if life came from matter.
The struggle against death, and the very nature of the evolution of species indicates quite the opposite. Organisms struggle to stay alive - and evolve in order to stay alive - because the element of life is not a physical element.
The fact that a Powerful and Omnipresent Being, coming from the spiritual dimension, produced the physical universe and impregnated it with life is the only scientific conclusion that maintains the laws of nature.
