I am totally ignorant of a dome.
Well, sure - because we are used to our modern view. But that's not the view described in Genesis, and throughout the scriptures. The scriptures repeat over and over that the world is described as flat, under a hard dome (firmament), under water. That's because that's what people thought back then, and our glorious God talks to people in ways they will understand. You can see a picture up in post #2 which makes this easy to understand.
You can see this by reading Genesis and these other scriptures (I'll list some more in a minute). As mentioned before (and backed up with a published paper), biblical scholars, who have studied this their whole lives, are clear that the Bibles describe a flat earth, under a hard dome, under water.
Firmament means "hard dome". That's why it has "firm" right in the word.
Here is the NRSV, considered by scholars to be the most reliable translation:
Gen 1: 6-17
And God said, “Let there be a dome in the midst of the waters, and let it separate the waters from the waters.” 7 So God made the dome and separated the waters that were under the dome from the waters that were above the dome. And it was so. 8 God called the dome Sky. And there was evening and there was morning, the second day.
.... And God said, “Let there be lights in the dome of the sky to separate the day from the night; and let them be for signs and for seasons and for days and years, 15 and let them be lights in the dome of the sky to give light upon the earth.” And it was so. 16 God made the two great lights—the greater light to rule the day and the lesser light to rule the night—and the stars. 17 God set them in the dome of the sky
Other translations use words like "firmament", and "vault", both of which also mean "hard dome".
People sometimes try to deny that the Bible describes a dome above us - because they think that our God has to describe our modern view of the solar system when he's talking to ancient Hebrews. It's really just that they'd rather that they could re-write their Bible instead of letting God speak to us in his holy word. You can see that on this thread.
I feel that space was first the God spoke and it was created
I think that's pushing our modern view onto the text. I don't think that the Bible itself ever says that God said "let there be outer space" and it was created. What verse were you thinking of, specifically?
As mentioned above, here are some of the sections that show the worldview of a flat earth, under a hard dome, underwater (below).
In Christ Jesus-
Papias
Flat Earth-
Bible tells us that the earth is flat like a piece of clay stamped under a seal (Job 38:13-14), that it has edges as only a flat plane would (Job 38:13-14,.Psa 19:4), is set on a foundation, like a table (2Sm 22:16, Ps 18:15, 102:25, Pr 8:27-29, Is 48:13), has a length as only a flat plane would (Dan 4:11, Job 11:9, Job 28:24, Job 37:3, Job 38:13, Job 38:44, Jrm 16:19), that it is a circular disk (Isa 40:22), and that its entire surface can be seen from a high tree (Dan 4:10-11) heaven (Job 28:24) or mountain (Matt 4:8) or which is impossible for a sphere, but possible for a flat disk. Taken literally, as the YECs insist we do, any one of these passages shows a flat earth. Taken together, they are even more clear. And many Christians in history have interpreted it as such.
Geocentrism-
The Bible describes the earth as unmovable, set on a foundation of either pillars in water (1 Sam 2:8, 1 Chr 16:30, Job 9:6, 38:4, Psa 24:1-2, 75:s3, 93:1, 96:10, 104:5, 136:6). It also tells us that, although the earth does not move, the sun and stars do move about it (Josh 10:12, Psa 19:4-6, 50:1, Ecc 1:5
(note “returns”, not perspective), Hab 3:11). And that the stars could be dropped down onto the earth like fruit falling from a tree (Rev. 6:13). Taken literally, as the YECs insist we do, these verses show geocentrism. And many Christians in history have interpreted it as such.
We live in a Planetarium (under a hard dome)-
The Bible describes the sky (firmament -- literally "metal bowl made by a hammer"- Gen 1:6-8, 1:14-17) as a solid dome, like a tent (Isa 40:22, Psa 19:4, 104:2, Pr 8:27-29, Ezk 1:26), that is arched over the surface of the earth. It also has windows to let rain/snow in (Gen 7:11, 8:2, Deut 28:12, 2 Kings 7:2, Job 37:18, Mal 3:10, Rev 4:1). Ezekiel 1:22 and Job 37:18 even tell us that it's hard like bronze and sparkles like ice, that God walks on it (Job 22:14) and can be removed (Rev 6:14). Ex 24:10 suggests that it is like sapphire. Joshua 10:12 estimates how far the Sun and Moon are from Earth’s surface. The Sun was stopped to illuminate the Valley of Gibeon, and the Moon was stopped to illuminate the Valley of Aijalon, showing that one wasn’t sufficient for both valleys (too close). So some basic trigonometry shows that they are therefore at a roughly similar height as the valleys are from each other – which is around 20 miles. Similarly, the whole Star of Bethlehem story in Mt (where a star designates a single house) makes no sense if stars are millions of miles across, but makes perfect sense if the stars are little lights hanging from a dome above us. Taken literally, as the YECs insist we do, these verses show a solid sky above us. And again, many Christians in history have interpreted it as such.
