Because they didn't know we were here?
Supposing you're exploring the galaxy, hyper advanced technology doesn't free you from efficient resource use as a priority until you can easily build enough to explore every star.
Given how many stars there are, I wouldn't be surprised if high tech civilizations still used the cheapest ships they could build.
I'd be curious if our EM emissions would have yet reached any potential source of the object...
