What would you have God do?

So we have God going about accosting people on grassy fields and demanding to know what he must do to prove his own existence. If I were his target, I would, after dilligently looking for the cameras, likely scratch my head for a few minutes and look confused.My first impression would be the excellent question chosen by many other posters; I would demand that he make me believe in him. On reflection, even that doesn't work.The possibility exists that this question could be just as easily be posed by some supernatural agency of great power who is not God. One presumes that such an agency could impenetrably decieve any human (as has been pointed in various ways in this thread by several individuals).Given this possibility, any proposed test can be met by the counter argument "Couldn't X just make you believe that your test has been met?" (where X=the devil, aliens, etc.)There is nothing that this deity could do to convince me.
