You chided me for playing with symantics, but now you are playing with symantics.
There was a fairly lengthy period between the general acceptance of the heliocentric solar system and Newton's equations for gravity. During these centuries, the only advantage of heliocentrism was that it simplified calculations -- and that only after Kepler.
There are always periods in science when paradigms are accepted without the seal of formal proof.
My point is not that everything some claim is science is not science. Indeed my challenging of evolution sort of shows that. My point is that science has indeed proven some things with certainty. My two examples which cannot be denied - the Heliocentric theory and the genetic theory have abundant proof behind them.
