I think it's rather problematic to attempt to explain topics of the metaphysical realm (the existance of God) with phenomens observed in the realm of physics. In this particular example, there are multiple gaps in the logic utilized.
The article assumes that the Schrödinger equation is an accurate representation of what happens in the realm of physics. Which is, of course, not granted. It's just a theoretical construct that - at the moment - serves as the best explanation we have of what happens so far.
From that assumption he describes a problem that appears: The sudden "jumps" in probability from 100 % to 0 % that the Schrödinger equation doesn't describe.
And here, we're arriving at an old philosophical question: Does a falling tree make a sound when no human being is around to hear it?
As paradox, as it might seem, the answer of philosophers such as Kant and Schopenhauer would have been: No. Why? Following Kant, things like "time" and "space" don't exist, but are just parts of the human perception of our universe. Thus, when no human is present to perceive something, it doesn't really happen. Of course, common sense dictates, that a lot of things do actually happen without any human observer, yet, unless some human is there to witness them in one or another fashion (and be it by imagining them to happen), they don't really happen.
This also answers the question, why our universe - from our perspective - has a "history": Even though no humans were present for a rather huge part of it, we are retroactively making it "real", because of thinking about events and trying to find answers about what exactly happened. You could also say: The Big Bang didn't happen, before the first person imagined it to happen.
So the collapse of the wavefunction is not really something to "prove" the existance of god. It's merely a mathematical problem, because Schrödinger's equation just generates results with a probability between 0 and 100 % where human perception does just allow things to be either 0 or 100 %. If there was an instrument capable of making the "Superposition" (the overlay of different conditions of a physical system in QM) perceiveable to human beings, we wouldn't cause a collapse of the wavefunction any longer, because we could perceive things "as they really are".
But thus, a being not bound to the limitations of human perception (read: God) could very well perceive reality in the form of probabilities and hence avoid the aforementioned collapse of wavefunctions entirely - even if he does perceive / know everything.
I, personally, am more of a fan of the decoherence-interpretation, though. It says that the collapse of the wavefunction doesn't need to be postulated, because it will be the approximate value if one considers the inavoidable interaction of a physical system with its enviroment. Which means, if I understood everything right, that stuff eventually happens, even if there is no human (or any other observer) around to check if it did happen. 😉
