Some of the problems we've learned were about how mutations are generally harmful and that they never been known to add new information.
What text or what teacher put out that "no new information" bull? I don't think you heard either of the claims in that sentence in an actual biology class, unless your teacher has fallen under the spell of the Creto-ID axis. It's been known for decades now that most mutations are neutral.....and what's this "life come from nothing" stuff, too? That sounds more like Answers in Genesis than a classroom to me.
