That sounds like ants reasoning "there's no reason for humans to mess with our ant hill. There's all that land right over there, and they won't have to fight us for it."
If the aliens are millions of years ahead of us, it's pretty optimistic to think they'll take us into account at all, unless maybe as a mildly interesting subject of nature documentaries.
I guess beings so strong and powerful that they would destroy us without a second thought, like we do to ants, would fall into the "Evil" category in my comment above.
