"the geometry of spiders' webs" Pretty sure that has nothing to do with interpreting a sphere. Your argument makes no sense. [quote]If God said "sphere" to humans before geometry was invented, how do you think the humans would have taken it? [/quote] You start with this. So basically people didn't know what shapes are because "geometry" hasn't been invented. Then you say this. [quote]So of course it is stated that the earth is a "circle,"[/quote] If people didn't understand shapes like you said, then telling them it's a circle wouldn't mean anything to them either! That would also just sound like gibberish to them by your own -blam!-ing logic.
