I just realized that you are arguing at the same
time, that scientists do, and don't, have absolute
convictions of certainty. Hard to lose an argument
that way, eh?
Yes, that tends to be the way they present themselves. When someone makes a statement without qualifiers, what does that make the statment? A "fact?" What unnamed assumptions are behind that statement? Every declarative statement carries a certain burden of proof, and a certain degree of assumption. It is no shame to science that it carries varying degrees of certitude in the staements it makes, but it is a shame they maintain an air of certitude as if their statements are wholly matters of fact.
But I would not be right to paint all scientists with the same brush. Dogmatic evolutionists exist, they have their convictions, and I am happy to hear them speak their convictions in the public arena. Far be it from me to accord them a sole voice.
