Here's a quote from St. John Damascus (Saint and Doctor) to prove you wrong about Basil's supposed ignorance of what Moses did. He was considered quite competent to a saint who wasn't tainted with your bias.
This quote and the one below will show you another Sainted Father who considered this matter as inconsequential. God as Creator and His awesomeness is what is important.
John of Damascus suggests that Moses thought earth was a starless sphere, that is, a globe. Yet we know that isn't the case. And he says St. Basil was "versed in the mysteries of divine Scripture." But we aren't completely certain Basil believed the earth to be a globe. Yes, Basil's chosen quotes indicate he believed in spherical earth, but we do not know for certain, having not read all of his scripts. In fact, your second quote proves my point because you missed the point of what was being said. There is a second possibility as well. Many saints seem to teach that there is a baptism of desire, yet they contradict themselves in their other writings. St. Augustine comes to mind. St. Basil bears more scrutiny for sure, since he was versed in the mysteries of Scripture. Another excellent post.
John of Damascus is talking flat earth in the second quote, and only distinguishing between details within that model. He speaks of heaven as a sphere at the beginning of the quote, then later, that heaven is a hemisphere.
They say, besides, that the heaven encircles the earth in the manner of a sphere, and bears along with it in its most rapid revolutions sun, moon and stars, and that when the sun is over the earth it becomes day there, and when it is under the earth it is night. And,
Others have pictured the heaven as a hemisphere. He is not even speaking of earth being a sphere, but heaven being a sphere. This doesn't even address the globe earth, but he is discussing the different opinions regarding the flat earth. Notice he talks about the vault, the curtain, tent, etc. All of them are flat earth references. His point is, no matter the details of flat earth, the earth doesn't move--which just so happens to be a notion that belongs to the globalists.
