@prothero,
Some of us believe that the whole universe and its contents are mind made, much like our dreams at night.
To look for God in the universe may be like looking for a needle in a haystack, because such proofs being exceedingly subtle and easily over looked would also be equally difficult to express and/or convey to another. In most cases it would prove to be a waste of time.
On the other hand, we cannot jump to the assumption that anything not found within the mind is therefore non-existent.
God (the Ultimate Self) is said to be outside of the purview of mind, and yet definitely ‘Present’ to some of us. How is this possible?
It is possible because, who we are is our most Essential Self or God/the Ultimate.
So, where we should be looking for this God/Ultimate Self is right at our very own self, and not letting our selves be side tract into looking everywhere in the big universe for Him. This would be a daunting task at best.
We don’t have to do this endeavor all by our selves. We do have helpers. People will come along, sometimes a book, and lend a helping hand, (People in the now and/or down over the centuries), who did what we are doing (exactly as we are doing it) only before us with some measure of success.
They will tell us things like “look within,” and “find what seems to be Eternally Present” (or what doesn’t come and go like everything in the mind). Simple statements like these, if taken serious and pursued with some diligence can take you very far, and finally reveal what is essential to you, your very Self/God. These statements serve us like turning on a light in a dark room.
There are those say that without material proof to keep us anchor in the real world, we will dance off into never/never land all by our selves. But I say that, with such consensus by millions of people over a long number of centuries, that I am not alone in my thinking or my accomplishment of both finding and knowing God/the Ultimate Self.
