a circle is a 2-d descriptor; not a 3-d form. you are describing a disc (the proper 3-d term) earth, not a circle earth. a circle earth would only be 2-d.
there is a word for "disc" in Hebrew and it is not the word Isaiah chose. the 2-d projection of a globe is a circle. a globe is therefore "circular" in geometric nature. the truth is not inconsistent with scripture, but your view is, and your view is inconsistent also with reality and observation and physics.
that God looks over the "circle" of the earth means that His view encompasses the earth, not that the earth is two dimensional.
