Pythagoras speculated but it wasn't recognized as proven till the 2-3rd century. Isaiah recorded it as fact long before that.[/quote]

It is fact that the authorship and when Isaiah was written remains controversial. That you would cite Isaiah recording the earth as 'spherical' previous to Pythagoras without acknowledging the scholarship behind questioning when the book of Isaiah was written is plainly disingenuous.
