"I do not have enough time... to actually verify what scientist have told me,
I guess you can call that faith, but it's entirely different than religious faith because you *could* verify (or falsify) what the scientists are saying. And even if you don't do it yourself, others will, and will build on this work.
Neither your mother nor you nor anyone else could do that for religious beliefs. Religion is set up and religious faith is defined to make that impossible.
So your "faith" in math and science has little to do with your mother's "faith" in her religion.
