I picked answer #3 because I'm ornery sometimes.
I think back a few years ago when Stephan Hawking boldly announced that he could find no need or evidence for God. Many theists pooh-poohed his conclusion, and many atheists said, "Well of course he found no evidence for God."
As a thought experiment, consider what the responses would have been if he had instead boldly announced that he indeed found a need for and evidence of God. I think a good many people, even if he was able to show the calculations, etc., would say, "Well, Hawking has gone off the deep end! We'll have to demonstrate why his conclusion is wrong," and then set to work to do just that. I would think that most physicists, at least at first, would refuse to accept his evidence and reasoning, and even if it stood up to scrutiny, would still work to undermine his conclusion. After all, he also believes that there are aliens, and that they are likely out to destroy us. I would suspect that his reputation would be tarnished, and most other physicists would no longer take him seriously, at least in the short term. Others would welcome his announcement with, "See, even a great physicist like Hawking sees the need for God! We are vindicated!"
