Seeing is believing 英文諺語
Seeing is believing 百聞不如一見，眼見為信
It is hard to believe something you have not seen. (Implies that you will not believe the thing under discussion until you have actually seen it.)
The phrase “seeing is believing” is well known to us all. It suggests skepticism; it implies that we will not accept the truth of something unless we can somehow see it. While the phrase may validly express a concern for verification, it contradicts basic religious ideas.
