maybe reapers are from a timeline where they didnt exist so shepard never made peace with the quarians and geth. so the geth evenually evolved into the reapers and conquered that timeline. then they created cross-dimesional teleporters and came to the ME timeline. all that BS the space kid said was to cover up their real story.
