But how does the possibility of the earth being a sphere undermine God as creator? Someone had to create the sphere. I don't get it. Geocentrism I can see. Flat Earth vs. Sphere? I don't see the philosophical ramifications of it. So long as this sphere is at the center of God's creation, what does it matter?
What's underneath this flat area? If you say hell, then what's underneath that? I have no problem with the notion of a grand universe that spreads out all around the earth.
I certainly keep an open mind about flat earth, but I have not seen any convincing evidence for it. As for Geocentrism, there's a LOT of compelling evidence in its favor. It almost seems as if Flat-Earthism is a distraction from the real issue of Geocentrism. It's easier to discredit Flat-Earthism and more people think you're nuts if you go there, so that even legitimate arguments in favor of Geocentrism are discredited ... when coming from the same people.
I'm not sure that I can explain it very well, but here's the Ancient Hebrew concept of the universe. I don't know how to embed a picture, but here's a link:http://www.patheos.com/blogs/religionprof/2012/11/ancient-hebrew-cosmology.html
The foundations of the earth are below, as is shown, and I assume that it's rock or earth. And then there's sheol, or hades. And then there's the Great Deep, but I don't really know what that is, exactly. The picture is based on the Book of Genesis, mainly. We can see that Heaven is just above the earth. But where is heaven, exactly, on a globe earth? Does heaven surround the globe? It doesn't seem likely, but it's possible.
We see that God is above the earth, along with the gate of heaven. On a flat earth, based on scripture, we can see that our earth is special, and unlike other planets, which are embedded or up close to the firmament, as is written in scripture. Scripture refers to the waters above the firmament. This is shown in the picture.
Secular humanism, with the current modern cosmology, teaches that we are just another planet in the universe, and although there's life here, there's probably life elsewhere. Current scientific cosmology rarely admits to a Creator. That's easier to do, when we're viewed as just another planet in the universe. Geocentrism does show that we are special by the fact that we are the at the center, and that the other planets revolve around the earth, but that doesn't go far enough.
