I wonder, what with the evolution of super-natural texts. How long it will be before a new, more our time-frame, with modern countries and technology book of God is 'published'. What will this new God be like? almost certainly nothing like Zeus, Allah or Jesus. No doubt however it will demonstrate beautifully how are evolved brains can adapt.
But to the latest Jesus followers, when God stopped being audible to people, did he throw them a book?
....or did that have to wait to be evolved from the human brain....
