They still rely on sound premises, which require some level of evidence. Without that, all the logic in the world won't get you to a sound conclusion. You have to start with what we know to be true in order to come to conclusions about what else may be true through logic.
I would agree, that an argument is only good as long as it's premises are true and it's logic is valid. However; and I'm assuming you are requiring evidence, that you mean physical evidence, that you will need to give evidence for.
