makes no sense to me to think a civilisation capable of interstellar travel would have any problems about their resources.
Then maybe they may come looking for an entire planet to colonize and not just the planet's resources.
For example, say the Earth's atmosphere and gravity are very similar to their own planet, AND their own planet (plus other planets they may have
colonized in the past) are becoming overcrowded. They could want the Earth simply because it is in range of their space-faring technology, and they
need the elbow room.
