A true scientist always has to hold out the possibility he is wrong...because there is no way to test for all possibilities. Science is never settled.
A brutal analysis of your statements mean scientists must have faith in what they currently believe is right.
Its the same kind of faith people gave that believe in God, because believers don’t have blind faith either, its based history and evidence as well. God doesnt demand blind obedience and faith in him without evidence
Modern secular scientists just prefer to put their faith in ever changing science instead of God. Past scientists saw the order and logic and saw God from their observations.
What it really means is persons interpreration of things based on what they are desirous to believe will influence how they see “evidence” for what they want to believe.
