Nothing material on earth you can’t find everywhere else, the only things we have that aren’t incredibly plentiful elsewhere are earths unique biology and human culture. Both of which can also be obtained without us ever knowing about it.

They might want the resources of earth.
There is also a chance they might want to hunt and/or rape us for the fun of it.
