Science could be considered a 'faith' of sorts, as we cannot hope to prove every little fact of science to every individual - some facts and equations we just have to take as true to keep forging ahead.

Science, however, encourages (and forces) introspection, and often changes its 'beliefs' to better match the world. True religions do not do this.

Also, the fact that what science discovers actually corresponds to what is measured much of the time, as well as the fact that science can predict events and important happenings, makes it the winner in my book.
