If there are intelligent aliens I fully believe it would take humanity ages to even realize they're intelligent. They most likely won't look like us, communicate like us, or live like us and we'll probably just assume they're funky looking wildlife and treat them based on this assumption. Hell, look how long we lived with crows and only in recent times do we actually take their intelligence into account.
If they are kind of like us I'd imagine our presence alone would bother them. Let's face it. Humanity is loud, obnoxious, elitist, and stupid. They'd see through the "we just want to be friends" attitude pretty quick and want us gone. Only after being rejected several times and given permission to harvest some of their resources would we leave them alone.
