It doesn’t seem likely to me that a civilization with the ability to travel interstellar distances would have any use at all for our planet or resources. I mean, the amount of matter in “empty” space between them and us would be enormous. What would they need our little rock for?

Not to mention the impracticality of communicating with your home planet across several light years.

If you’re basing this off of what’s happened in the past on this planet, without a good explanation as to why that would apply to an alien civilization, I’d suggest that you’re not using a good model. Bayesian epistemology is not a good way to decide what’s true, because new knowledge is created which makes the old models not work anymore.
