It would be as tempting as for us to go and observe some ants. You'll eventually get bored of them. They're not interesting. Now, imagine a civilization which is able to travel among galaxies. How intelligent would they be? We would be literally ants for them lol.
As for our planet resources, sure, if we're in the way they'll just make us go extinct but not because they hate us or something like that, we're just...in the way.
I wish I could feel more special as a human being but the more I learn about science and this universe, the more inferior I feel haha.
Edit. Here's a video of Michio Kaku talking about aliens. I really agree with him.
