First of all, "ten hundred thousand" isn't a real number.
Second, it is fact that the halos were last activated around 100,000 years ago: "Installation 04 is confirmed to be, at the minimum, 101,217 local years old, a local year being the amount of time it takes Threshold to orbit its star. In an interview with Joe Staten of Bungie Studios, Staten also confirmed that the previous firing to which 343 Guilty Spark alludes occurred around 100,000 years previous to the events in 2552 at Installation 04."
100,000 years is not long enough for humans to have evolved from lower life-forms; meaning we must have existed before the halos were last activated, which contradicts your theory.
Also, if the covenant learned our language from watching us, why don't they speak French, German, Russian, etc.? The language part is irrelevant, the only reason they speak English in the game is so we can understand them.
