- IN THE SENSE OF SPHERE
You do not understand how language works. A word can be used in many ways. You set up a paradigm that demanded only ONE definition, and only the one YOU wanted. Language does not support you at all. Yes, a circle can be defined as a 2 D space. But this page shows the myriad of possible meanings for the same word! Even the Bible uses different words in translation, which are far different than your elementary arithmetic geometry. But I leave PH for the math comments.
Your whole theory of a flat earth, is based on ignoring the basic fundamentals of exegesis. It is also based on not understanding the diversity and richness of the many definitions of a single word. You are WRONG! The earth is not flat! It is round, goes around the sun. This has been know since forever, and codified by Copernicus.
