Just to be clear, an atheist is not someone who believes in science. An atheist is someone who doesn't believe in a god or gods. When Catholics have a baby, that baby is an atheist when born because he or she does not believe in a god or gods (because he or she is not capable of doing so). As the baby grows up and learns from his or her parents, he or she will be indoctrinated into the Catholic belief and become a Catholic theist.

Let's also make the difference between believing in science, and believing in what a scientist says. It seems rather silly to say someone "blindly believes that things aren't true unless there is evidence for them, and if evidence contradicts something then it can't be true".

However "blindly believing something just because a scientist proclaims it to be true" is, indeed, pretty stupid. Of course with science there is a way from going from a scientist proclaiming something to be true, and determining if it is or not (to the best of our current understanding). That's the whole point of science.

Religions on the other hand say: believe this religion, and this religion only, without any evidence, and if you don't you're going to be punished. There is no way here to question if these beliefs are true or not. You either believe it (and are presumably punished by every other god out there) or you don't (and get punished by all the other gods out there plus this one).
