One of the theories floated is if an advanced civilisation made it to us, they would most likely be so advanced they would see us no differently as we would view ants and not even consider us if they needed any resources from our planet.
Another thought is the fact that no advanced civilisation has ever made it to earth is proof that any intelligent species is destined to destroy itself before it can evolve far enough to travel the stars.

Looking like our planet might prove this one to be pretty close to accurate at least in our case, within the next hundred years or so. If not from nuclear war then from running extremely low of key resources on the planet and suffering a massive conventional war over the remaining resources.
Freshwater alone seems like it can cause it. We already have major cities almost entirely running out of fresh water (see Mexico City this year). Western US came worrying close with Lake Mead's water level a couple years ago too, but thankfully it eventually started raining enough to replenish it again.

Sorry, but modern Doomerism needs at least a dozen more orders of magnitude on its confidence that we'll all die before it can claim any part in Fermi's paradox.
Or it could be that inflation never ended and there’s a rapidly increasing number of vacuum collapse bubbles inside it, like ours, in which case approximately every civilisation is the first to exist in their bubble.
Another thought is the fact that no advanced civilisation has ever made it to earth is proof that any intelligent species is destined to destroy itself before it can evolve far enough to travel the stars.
Both outcomes are pretty bleak
