"The Derilect Reaper is 37 million years old, the Protheans went extinct only 50,000 years ago" you're thinking backwards, they went EXTINCT 50,000 years ago, they weren't born 50,000 years ago they only went extinct, who's to say the Protheans weren't around 37 million or more years ago, I mean look at some of our animals who've been around for a while, I think there is some pretty damn accurate data showing that dragonflies were around when the dinosaurs were around too, which means over 136 million years they've been around. It'd be silly to think all the reapers are protheans, but there has to be some prothean reapers. Sovreign, Harbinger, Derilect Reaper, it's completely possible they are prothean reapers, but it's also possible they aren't.
