Uh, since the Christian states he/she does not believe in Thor, I would say that would be evidence that he/she is NOT a Norseman. Perhaps that is what you meant to state.
At any rate, yes, no matter what position on takes as regards to God, it is a step of faith. Some positions have more evidence than others, but it is a step of faith none-the-less.
Under these criteria, it takes just as much faith for a Christian not to believe in Thor as it does for an atheist not to believe in God.

Not really. An outlook is to say that it doesn't exist unless the existence is shown sufficiently. Almost any adult will state that Santa Claus as a person doesn't exist because of lack of proof and simple logical analysis of the claims. Same thing with some atheists.
