Anon, the Forerunners are vastly superior to the Reapers they can easily wipe them out. About the only thing that managed to defeat the Forerunners were the Flood and that was because they used their own technology and people against them. Also can't forget the help from Mendicant Bias against the forerunners and their Mantle. Even the Flood is stronger than the Reapers and they're a parasite.
