It's not necessary to believe in a god to believe in absolute truth. There are other philosophical bases for such a position.Wrong. Plenty of philosophies have been constructed on the basis of conditional or locally valid premises. More importantly, that's the way real people really think most of the time: nobody waits to determine the absolute truth of the weather forecast before deciding to wear a coat. One of the ways humans can still beat computers is that we can take decisions based on uncertain or incomplete data, which hangs up brains based on pure logic.Without absolute truth there are no premises for thinking, which means there is no logic which always depends on premises.
And your evidence for the nature of god is what?Get over it, thinking is what makes you human and in the image of God, like it or not.
