Plus, throughout the ages, humans always used numbers to their advantage. Hunting parties are common place. And considering the advantages that Predators and Xenomorphs have speed, stealth and strength wise, humans wouldn't stand a chance by themselves.
Humans use tactics, cooperation and communication to their advantage. It's also technology which helps us survive up against such a strong enemy.
I get that people would prefer this to be Aliens and Predators more then humans, but every movie, whether it be Alien, Predator or Alien vs Predator, show that humans were an important part of the triangle. We know other aliens not of the Xenomorph variety were around, but they focused on the main three sides. Predators used humans as incubators for the Xenomorph chest bursters, so they could hunt etc. It's only natural that we RP a part.
Malus is right, we feel more like we are fighting for ourselves as humans, although being a Pred or Alien would be awesome as well. None of this is for a particular person, and none is said in an angry or bad manner. So please don't see this as picking on one person, or on either side.
