[MHGinTN]

You used the term in a temporal sense trying to juxtapose the universe with ‘eteranally existing dimensions time and space, as if these come ‘before’ (a temporal term) the god you wish to disabuse as creator of time and space. You are clever, but not as clever as you presume to be. Again, you assume the assertion that god is not eternal, then assume that space and time are eternal, then you try to draw a conclusion that god cannot create ex nihilo because soemthing must pre-exist the creation of this universe. Your whirling dervish act is amusing, but rather transparent. Have a nice day
