You don’t need to counter his argument, instead, ask for that evidence he is talking about, and ask him to show how that proofs the existence of God.
But, should you not be learning about physics? Is he such a great teacher of physics that you have to put up with his erroneous notions?

Pretty sure you can find quite a few nationally know physicists who are atheists and could argue the case against him. My guess is he has spent a lot of time cherry picking his data. But that's just a layman's observation.

Why is there sin and why do we sin? Sure free will but will to do wrong is counterintuitive is it not?

I state often that everyone has an opinion and your physics teacher has stated his. In my opinion, people who become atheists will live a happier, more productive life because they are independently free to do so.

Is it even legal for him to push his religion in your class?

The term "physics" covers a very broad group of scientific disciplines. Can you be more specific, In what area does this person teach?

I'd watch this then ask him why this presentation (points given) are wrong.
This one is better. Lawrence Krauss is theoretical physicist and cosmologist who previously taught at Arizona State University.

I've always observed. If you're devout in your religious beliefs you shouldn't be teaching the sciences or history.
