But what confuses me is that, while I choose not to believe in this teapot, I also have some faith that there is probably no evidence ever to be discovered for it.

Do atheists also have faith that there is probably no evidence awaiting discovery for theism?

You can be open to the possibility of that which is unproven without actually believing it.
