Aliens would indeed not travel to us for earth's ressources. But our earth is special by the existence of life. If life emergence is a random process, the forms it can take may be as well. There would be alot to learn and gain from a direct access to it. Science and knowlege is the ultimate ressource any ciilization will run after, after energy and other limiting facors have been mastered. Another frequent mistake is that ET would travel direct from home to earth. As far as we know FTL is impossible. So it makes better sense to travel by small hops from one solar system to the next one. It could be more a ant like colonization process. This would imply that ET visiting earth would irst build one or more bases in our solar system and visit earth from there.
