Viewing the universe as a timeless four-dimensional object—rather than the temporal evolution of a three-dimensional one—does not really buy you any “simplicity”—because then you need an additional explanation of why the four-dimensional object is structured in the way that it is.
you also need to explain motion which does not exist at all in a timeless 4d object. you need to explain how any static being can experience a present moment and moments leading up to it as past moments. and you need to explain how any perception is possible by a static being.
