[MARVEL] Shouldn't most of the universe be absolutely terrified of earthlings by now

Like earth power level is busted. Even though most of earth is lower the a type one civilization. They have a ridiculous amount of cosmic level beings on one planet and a bunch of geniuses that can bend science into whatever they want.Not to mention they literally have actual gods and advanced magic on their side.

They have already beaten some of the strongest army's in the universe and taken down cosmic gods that have terrorize the universe since the beginning of time

I think on the comic scale earth is probably the biggest threat to the entire universe.

Earth itself, and its people, are really not that serious of a threat. Most of the universe tries its level best not to kick the fucking hornets' nest, and most Earthlings are only passively aware of a wider cosmic community beyond their planet. Most heroes and villains either don't have a reason to go out into the wider universe, or don't have the means to do so. 

Yes, some Earthlings CAN do some pretty incredible things and YES some of the things those individuals might choose to do can have devastating effects on the universe at large, but more often than not these individuals either don't care about the broader cosmos, or wind up self contained by the efforts of other Earthlings. 

So, Yes, Earth is potentially very dangerous, but really it only shows up on the wider cosmos when some arrogant fucknozzle with more ego than brains decides to throw down with the Florida Man of this particular branch of the universe.
