[Marvel] How is Earth able to keep up with all the alien civilizations around it?

Clearly, the Marvel Universe's version of Earth takes place in the present, but it is surrounded by all sorts of interstellar races. You'd expect the planet to be as significant as a speck of dust. Instead, it's able to fight off any alien invaders. And that's not counting all the superhumans and mutants that live on it.

How is this even possible? Shouldn't this be like a primitive tribe going up against the Army? I imagine aliens in the Marvel Universe having tech way more advanced than the stuff guys like Iron Man has.

Sort of. Now imagine that primitive tribe has a number of shamans who can summon dragons, call down lightning on their enemies and read the minds of the enemy generals. And imagine that their tribal god is a real, corporeal entity who takes the field during battle and he can take out tanks and fighter jets all on his own. And imagine that a few of those tribesmen, despite still being at the bow-and-arrow stage of technology, are smart enough to meaningfully understand and analyze the army's modern technology with only a couple of days of study. Oh, and the tribe doesn't need to completely defeat the army. They just need to make it too costly to justify the invasion. That's Earth in the Marvel Universe. Any alien with good sense is scared to death of that place.

When the Skrulls invaded the Earthlings sent a hit team to *murder their gods*. Gladiator of the Shi'ar Imperial Guard can conquer planets on his lunch break and Earth's heroes use him as as punching bag. I've lost track of the number of times Earth has beaten down Galactus. Some rando human made Ultron and that thing became a galactic threat. Almost everyone who's held the Infinity Gauntlet was from Earth or one of its colonies. They pretty much trip over Cosmic Cubes. Earth isn't even the underdog anymore.
