Evolution is at least as much an amount of faith as Creation is. Actually more, because we have the Word of the Eye Witness.
“Science” is about observation and prediction - of things in the present. So neither evolution nor creation can be proven with science, since both are describing a one time event.
Of the many incorrect statements you two have propped each other up with, my favorite is “neither evolution nor creation can be proven with science, since both are describing a one time event.”
Painful. This perhaps explains why some creationists conflate their creation myth with evolutionary theory; they think (for whatever reason) that evolution happened once many moons ago and that was that.
(And they also think scientific theories are “proven,” but that’s mere semantics.)
In saying as much, one quickly exposes himself as having absolutely no idea was one is arguing against.
