@3point14rat - I think you might have just asked the question of the decade if not - the question of the century.
What are aliens doing here?
Assuming they are here. So this is a question for the believers. (I am a believer too)
Because you are right - if you think about it, we cannot be of any interest to any advanced alien civilization.
But they are here! (They say). So… we are of interest to them?
Which sounds a little scary.
I can see far more bad scenarios why we would be of interest to them than positive scenarios.
