The star is also pretty insignificant compared to the whole universe to be honest. Almost everything is at that scale.

And I mean okay, alien intelligence life must be very smart and not contact us because we are so evil and petty and self involved etc. And every single living species we encounter is also the same. Why are we grandstanding these aliens? They are likley sipping coffee in their corner of universe and wondering man why do we keep doing all this nonsense when we are so insignificant etc. That is far more likely to me than aliens who know we exist but willingly stay away because we are humans.
