That is my first thought. A civilization that has mastered interstellar and/or interdimensional travel would probably give us the level of attention and interest that I give an anthill in the woods behind my house.
If it's a fire ant mound that encroaches into my yard, yeah, I would perceive a threat and deal with it appropriately, but otherwise alien technology would probably be as far beyond our scope as my car and computer are beyond the grasp of the ants in the woods.
Yep.
More removed than an ant hill. As the drill sergeant makes clear, "You're whale s**t, so low you're on the bottom of the ocean."
