I have my own theory, copy pasted from another thread.
You see, eons ago, there existed a race that spanned the galaxy. Before the Protheans, and before the dozens to hundreds of galaxy spanning races before them. This race, far advanced beyond anything we know, was afraid. They had spent so long, and worked so hard to achieve their place in the universe, but they knew it would not be eternal.
So they turned to machinery, shedding their mortal shells to live on forever. Bodies would no longer age, the mind could be backed up and preserved forever, their legacy, would never end. In this, however, they were still not perfect. A few individuals wished to continue life in their pure organic form, to live and die as they always have. The downside of overpopulation due to a high percentage of immortal individuals became almost immediately apparent. The leaders of this civilization then game to a conclusion.
A superstructure, far beyond any former synthetic body, was proposed. With it, all the nations of their great civilization could be preserved. Volunteers from all accross the galaxy had their bodies processed down to join the collective conciousness that would, eons later become known as the first of the Reapers.
As the Reapers were completed, those that remained grew fearful and mistrustful of these great beings. Scientists and philosophers that stayed in the organic state reached a conclusion that their synthetic bretheren would turn on them, claiming their decision to remain organic, to live and die as evolution dictated, was a waste of the valuable resource their collective conciousness could provide.
Their fears secured that outcome, as war erupted between the reapers and the organics. Irrelevant of who struck the first blow, both sides suffered heavy losses throughout, until the reapers devoloped methods of control to use on their organic opponents. The first instances of indoctrination were quite easy, since the Reapers understood just how the organic minds of their enemies functioned. Nanomachines invaded select hosts, and were released as sleeper agents into the armies of the organics. Following which, the defeated army was forcefully processed down into reaper shells themselves, connecting directly into the shared conciousness of those they called enemies and coming to a shared conclusion.
With the entirety of their original species turned, the galaxy was still. Thousands of years the reapers spent, alone with their shared thoughts, contemplating the reason and outcome of the long war they had just fought. The conclusion came, that all organic life had failed, and their immortalization as a collective of machines was a fortunate exception to the never ending failure of evolution.
As new species' evolved and spread into the reaches of space, the reapers made the final alterations to the former center of their civilization, the Citadel, sending their forms off to Dark Space, while one remained behind. They would observe civilization, wait for its apex, then invite them to join them in eternity, in perfection. They would secure a valid future for life in their galaxy, whether it wanted it or not.
