The valid point here, to spell it out for you, is that the Bible does in fact reflect the flat earth and domed firmament cosmology of ancient Egypt and Mesopotamia. Scholars would agree. The only reason that you argue otherwise is that the Greeks have established that the earth is spherical for two millennia and half a millennia ago Galileo successfully argued against the then prevailing geocentric theology, and established that the earth revolves around the sun.
So over that past hundreds of years, theology has made its peace with the counterintuitive but scientifically established fact of heliocentrism. You do not feel the ground move, yet it does rotate and revolve. You can thank science for that understanding, or choose to ignore it at the cost of joining the looney flat earthers, many of whom base their belief, with solid textual justification, on the scriptures you yourself referenced.
So, despite your sanctimonious posturing as being faithful to scripture, you are not so different as you would like. There is an element of metaphor and deeper meaning in scripture, for you and for others. What we know of the world around us plays a part in how we approach the Bible. All truth is God’s truth, both revelation and nature.
