If you read the trivia section for the first AC game, I believe it establishes that I remember reading it somewhere on the Wiki as well, either on the Eagle Vision article or the AC1 article. I'll see if I can find a direct quotation. Okay, yeah, if you direct your attention to the Eagle Vision article, navigate to trivia, for the first game, it says: 

• In Assassin's Creed, Eagle Vision was said to actually be the Animus' visualization of the Assassin's observational skills.

So there was at least one point where Eagle Vision was explained to be the Animus's visualization or representation of the Assassin's observational skills. Likely Ubisoft did not envision taking the series to the extent that Eagle Vision would be a Precursor related ability. I don't know where in the game it actually mentions this, maybe in the manual. That's the only reason why I'm asking, because Bayek's Eagle Vision only highlights objects of importance, but doesn't highlight guards in the typical red aura.
