How is it that a scientist, "and a pretty good one" isn't aware that there is never proof of a scientific theory?

How is it that a logical human being, and a pretty good one like yourself, does not understand that where there is no proof there is faith?

How is it that a logical human being, and a pretty good one like yourself, does not understand that where there is no proof there is faith?

That's a false dichotomy: although scientific theories are never proved, they also never operate on faith.
