[Destiny] How many of them are there?!

I'm an average and rather exasperated Guardian and I know for a fact that many of us are busting our asses. The leaders of the Vanguard are telling us all about how crucial our victories are and how much of a difference we are making. Even with all the "progress" we are making every time I'm on patrol I see the same amount of enemies, I have over 16,000 kills by myself not including the Crucible and I'm a typical Hunter. I know they are thousands more of us and many of them are much stronger than I amand have much better records so why the fuck haven't we eradicated the Fallen, Vex, Hive, Cabal and Taken?

You are battling against interstellar forces, and in the case of the Vex, interdimensional ones. The Fallen are likely the least numerous, and probably still number in the tens of millions. For the Hive of the Moon alone, they undoubtedly can call upon billions of Drones.
