What is "seeing is believing"

prov. You need to see something to believe it; visible facts cannot be denied.

Seeing is believing is an idiom first recorded in this form in 1639 that means "only physical or concrete evidence is convincing". It is the essence of St. Thomas's claim to Jesus Christ, to which the latter responded that there were those who had not seen but believed. It leads to a sophistry that "seen evidence" can be easily and correctly interpreted, when in fact, interpretation may be difficult.
