Well, certainly all we can know about God is what he chooses to reveal through general and special revelation.
The point to that, is that it is not subject to futile speculations of the mind of mankind (which is totally futile in the end). What we know is revealed to us ... and thank goodness for that, or else we would be chasing our tails around in a circle just like these “scientists” who do so with their “fantastic speculations”.
“Thank God” for God ... :-) ...
