And I hear this all the time when YECs criticise people like Hugh Ross. They'll say things like, "prior to the 1800s that wasn't a view that anyone held".
And it's like, well yes and no. It's correct that belief in an old earth or belief in evolution or the big bang were not common in the church prior to the 1750s or so. But the obvious reason for this is that such things hadn't been yet discovered. It's the same reason that people in the early church doubted heliocentrism and or a spherical earth. We can't expect people to know things prior to their discovery.
But, what is necessary, is to take this a step further and to point out that the same thing applies to the Biblical authors. They didn't know things that hadn't yet been discovered scientifically.
And the Bible affirms this. Job 38:17, He spreads out the sky hard as cast bronze metal.
There was a commonly held view in the time of the ancient isrealites, that the sky was solid. And when we read the Bible, it's plainly evident.
And above the solid sky, was an ocean. It was an ancient explanation for why the sky was blue.
and they saw the God of Israel. Under his feet there was something like a pavement of sapphire stone, like the very heaven for clearness.
Exodus 24:10
God walks up on the vault of heaven
Thick clouds enwrap him, so that he does not see, and he walks on the dome of heaven.’
Job 22:14
you set the beams of your chambers on the waters, you make the clouds your chariot, you ride on the wings of the wind,
Psalms 104:3 (God's heavenly chambers sit above the waters)
Over the heads of the angels there was something like a dome, shining like crystal, spread out above their heads.
Ezekiel 1:22
He made strong the skies above, When the springs of the deep became fixed, When He set for the sea its boundary So that the water would not transgress His command, When He marked out the foundations of the earth;
Proverbs 8:28-29
And that's what these verses, among many others, are describing. A historical cosmology. And it's not perfect. It's generally phenomenological.
But it doesn't have anything to do with the expanse of the universe. Not that Moses and others would or could look up and see the expanse under God's feet if it were billions of light years at the edge of the universe anyway.
The dome was maybe a few miles higher than the tallest mountain. Stars were inside the dome, stuck in it so that they would not fall.
