I am sick of people comparing this game to Halo.
Halo starts when we are in the middle of a war, Destiny (as far as we know) starts after the war was lost. Halo we fight against a bunch of unified races as a super soldier. In destiny while the traveler gives humans power it can probably be assumed it gives all humans power thus making no human different from the next and the fact that the alien races in Destiny don't seem to be unified at all. Halo spans the galaxy, while Destiny spans our solar system. The ancient race who left ruinns behind in Destiny are the humans themselves. While the cannon of Halo does include ancient humans who were "destroyed" the humans you see in the games are in fact an entirely different evolution of humans. Destiny so far lies in mystery and we don't know what caused what and who is trying to kill who. It seems people are assuming certain things because they can link certain aspects of the story that we know to things in the halo universe when in reality we know next to nothing.
