You DID ask why God didn't use a word for oblate spheroid/why Hebrew had no such word.
What have we resolved or not resolved about my current claim? I claim the Hebrew word is "sphere"; you claim "disk". I also claim that Job predates the Greek scholars who measured the Earth.
There are no “ends” or “edges” to the Earth, BilliardsBall, if the Earth were like a “sphere” or “ball”. A disk have “edges” and “ends”.
“Job 28:24 KJV” said:
[24] For he looketh to the ends of the earth, and seeth under the whole heaven;
“Job 38:13 KJV” said:
[13] That it might take hold of the ends of the earth, that the wicked might be shaken out of it?
It is clear that who ever wrote Job, has no understanding of the shape of the Earth, and Job 28 & 38, prove that the Bible saw the Earth shape as being disk, not a sphere.
And from the view from Earth, man couldn’t see the whole universe, if “heaven” = universe.
Because of the human eyes’ limitations, we could only see a very tiny fraction of the Milky Way, unaided (eg naked eye, hence, no binoculars or telescopes).
Say you live in New York City, if you were to count the number of stars in your location (naked eye, of course), it could be anywhere under 3000 stars.
The Milky Way have somewhere between 100 million and 400 billion stars. From the above figures, it is obvious astronomers can’t tell exactly the number of stars, because our own Solar System is located on one of minor spiral arms of the Milky Way.
So our view are blocked by other spiral arms of stars and thick cloud of dust and gases, that prevent us from viewing the other side of the galaxy, as well as blocking the direct line of sight of the Milky Way’s bar-shaped core.
We only see a portion of the Sagittarius spiral arm (Carina-Sagittarius arm), which blocked our view, behind it. And behind this arm, are the Centaurus spiral arm (Scutum-Centaurus), and then the Norma arm (Norma-Outer arm). These 3 spirals are actually blocking from viewing the Milky Way’s centre.
And the only stars we can view are local stars, those stars on the Orion spur - which is where our Solar System is located - a very portion of stars on the Sagittarius arm that immediately blocked our view towards the centre, and a tiny portion of stars on the Perseus arm, from the other direction.
Slightly larger objects that we can see with the naked eye, are the Andromeda Galaxy (about 2 million light years away) and the Triangular Galaxy (over 3 billion ly away). But without decent size telescope, these two look like cloudy blobs, not spiral galaxies.
It took the year 1919, for Edwin Hubble to discover these two objects and recognize that Andromeda and Triangulum were galaxies outside of the Milky Way, and not nebulas within the Milky Way. Hubble was using a newly built Hooker Telescope (the Mount Wilson Observatory, California); it was the largest optical telescope in the world, at that time.
BEFORE 1919, every astronomers have assumed that the Milky Way was the only galaxy in the universe. Hubble’s discovery in 1919, changed everyone’s view about the size of the universe.
Since 2002, astronomers have estimated that there might be more than 100 billion galaxies in the observable universe. And it is quite possible that the universe could be even larger than the observable universe.
Despite how powerful our current technology compared to Hubble’s time, there are still limitations of what we can observe in our universe.
