ragiya and gravitons, implications

It is hard to list Man's most important discoveries. It is super embarrassing when we realize we keep learning things, then forgetting them only to realize it was all written down tens of centuries ago and we as a species were just too stupid to understand what was plainly written long, long ago.
Archaeology began as a science sometime in the 1600s. It's early goal was not just the study of ancient civilizations, but rather instead to construct a timeline of them that fit in with the Bible teachings of the Roman Catholic Church. Churches funded much of the early research and published many findings we know today to be pure balderdash. Originally church 'scientists' claimed Man was only about 5,000 years old as a species. Since this fit nicely in the Biblical timeline it was for centuries so taught in school. Later of course deductive reason, new concepts, and new discoveries had by the early 20th century resulted in teachings Man was 20,000 years old and reality conflicts with biblical timelines were blamed on poor translations and a lack of understanding of the Word. Again Balderdash.
Today we know more. We know human skeletons just like our own have been found and dated as being 200,000 years old. We know we coexisted side by side with various other hominid species on this world. We can prove sometimes Man and Neanderthal lived together and actually mated. We know something really bad happened around 85,000 BC and all the other Hominid species died and even we shrank from several hundred thousand pairs to only about 1,000 breeding pairs on the whole planet. Then came the last great ice age and whatever there had been went under a half mile of grinding ice that erased any traces of a civilization. Only o*al tales remained for a long time.
What of the Bible you ask? Well ignoring the events of the First Council of Nicea, at it's core the Bible is based on the old Hebrew scriptures. They themselves had been mostly o*al and weren't compiled and written until the 3rd century AD. Early church financed archaeologists had accepted the Hebrew as a historical account. Today we know that somewhere in changing from an o*al history to a written one many truths were forgotten or distorted by the committee that chose which lines to keep and which ones sounded better.
Even more shattering is the relatively (past 40 years) discovery that the Hebrew scriptures were and are simply badly plagiarized excerpts of older tablet texts of the Sumer people who had themselves expended great effort into putting everything known onto clay tablets (millions of them) and buried them in underground libraries. After the great flood when the ice wall holding back the waters covering Europe and most of Asia broke (around 15,000 BC) the flooded Sumer civilization ceased to be and refugees settled in what we later called Mesopotamia and Babylon and Egypt. Amongst the Sumerian refugees in Egypt was a man named Abraham. Things were happening in Egypt and what became Lebanon and the time of the great lament (millions dying) was at hand. Abraham tweaked some of the older teachings and came up with a short hand o*al history of what had been before. Today we call that Genesis.Others continued the work after Abraham had passed, but it was an o*al history passed down from father to son in continuously longer and longer recitals as more and more was added. Without boring details, the tribes of Hebrews split up and dispersed, so that 2 or 3 thousand years later there were different o*al history versions.
On of the very early Genesis concepts which has caused much debate is the use of the Hebrew word Ragiya. Loosely the word translates in English as firmament. You will find it early on Genesis 1:6 and up to about 1:20. In 1:20 we see birds fly UPON the ragiya, not in it, so the firmament is not atmosphere. It is not earth either as the passages describe the earth dividing the waters. .End part 1
