What most people seem to not understand too is that their trust in science is based on faith that the people carrying out the work are doing it correctly.
I'm not saying they aren't, just that it IS another form of faith as the vast majority of people cannot verify the scientific things they preach about, but take it on good faith that it is true.
Scientific research is subject to peer review and is heavily scrutinised, they cannot wait to find a flaw in someone else's work.
So unless there is some huge conspiracy that they have agreed to all lie, then they are doing it correctly.
