I'm not confusing them. But people who see it as a two-sided argument are. What you said about an experiment and having no idea sounds like my impression of the state of the science too. But you wouldn't know if from the news media which seems very sure of itself and very sure that things are going to be bad, and very sure that riding a bike to work or buying an EV will make us into good people. That's the problem I see.

AGW deniers, I think are hoping to derail the whole thing by showing that humans didn't cause it. But that's not the only skeptical view you can take. I think yours is about the same as mine.
