Are you suggesting that Galileo was not a scientist because his first hypothesis was wrong? Assuming that your version of the story is accurate, Galileo was certainly part of the scientific process. Even if he didn't come up with the "correct" answer himself, his hypothesis prompted others to question his reasoning and, eventaully, to propose better hypotheses.
Yes, that is how science works, by being wrong and then figuring out
why you were wrong.
