I have no opinion on it.
I don’t think such a question is scientific, but if I come up with an experiment, I will let you know.
The problem is the “G-d created the world 5 minutes ago with all the fossils in the ground” argument. Can’t prove it or disprove it. I do know that I don’t get phonecalls from G-d at work, or emails, but perhaps that is just me.
You asked for an experiment (#5) and got it. But I guess it was too complicated for you.
