I don't even have a good argument for this beyond asking for proof that God, or indeed anything, is circular in time.
Long answer:
Can you prove that time moves in a straight line?
Sadly, the only thing you can call the 'direction' of time is the change in entropy. Which would be fine, except that the statement "heat moves from hotter to cooler" is basically axiomatic: it could be the reverse, and you would never be able tell the difference.
"But I can remember the past, and not the future!" you cry, "and the passage of my memories show that the Second Law of Thermodynamics is valid in the manner of it's conventional interpretation!"
Well noted, but you have neglected memory skepticism: how do you know that your memories are even slightly legitimate? After all, the only 'record' you have are your memories, and if your assumptions about time were wrong, your memories of the 'future' would simply fade away on the universes march
toward the Big Bang [small](Big Crunch?)[/small]
And you would be none the wiser for it, for in truth you have only a single moment in time available to you: indeed, you are not reading these words. You are simply remembering the act of reading them, and what they meant to you. For all you know, there is no progression of time
at all, and all you have is this one infinitely small moment of time in which you experience your so-called 'memories' of the 'past', and start to realize that you know nothing at all for certain.
[sup]And don't even try to invoke Occam's Razor: Physics is so riddled with philosophical assumptions that you might as well invoke the Old Gods of Atlantis.[/sup]
Short Answer:
"Proof"?
Ha ha ha.
