Dear
Prim90,
I am not sure what you mean here, but it sounds a bit dour.
Personally, I don’t think the belief of a spherical earth or a heliocentric universe damages the credibility of scripture.
There are many things not mentioned directly in scripture that are generally accepted to be factual, an example is the existence of the house cat. Although cats are not mentioned in scripture, most people believe they exist without it damaging their faith.
More seriously, there are many subjects that the Bible does not attempt to teach directly. Arguable examples are mathematics, chemistry, biology or many other areas of knowledge that are generally accepted as self-evidently true despite the absence of comprehensive definitions or details in God's written word.
Therefore I think there are acceptable truths of nature we don’t need to dismiss out of hand and further, I believe we can entertain extra-biblical sources of truth, so long as they do not directly contradict scripture.
Back on topic for a moment, in the case of the earth's spherical shape, although scripture never explicitly states the shape of our planet or attempts to teach us the physical design of earth directly at any point, it does confirm a round earth implicitly in various places.
I once read an interesting paper that referenced the Creation account in Genesis 1. Here the Bible says that the earth began as water only, and water suspended in space always takes the form of a sphere due to the surface tensions of water molecules. Wow.
Furthermore, when dry land appeared, Genesis 1 describes all the land as existing "in one place" in Genesis 1:9 while all waters are gathered likewise. Geometrically, this can only happen on a sphere, and therefore Genesis 1 implies a round earth. Again wow, thank you God.
Ultimately, where this leaves the earth in the hierarchy of God’s universe is not as important to me as the fact that we were important enough for the Creator to send His only begotten Son here, to earth, to show us the narrow path and open the gates of Heaven for our salvation.
Thank you
Prim90 for the interesting perspective.
God bless you.
