Assessing existence while failing to embrace the insights of modern physics would be like wrestling in the dark with an unknown opponent.

I'd say many features of string theory don't mesh with what we observe in everyday life.

Intelligence is the ability to take in information from the world and to find patterns in that information that allow you to organize your perceptions and understand the external world.
