User blog comment:Garhdo/Why the Reapers attack Earth/@comment-217683-20110102194137

Well... an unregistered user said pretty much exactly the same thing on another blog yesterday, and I already answered it in depth there, so I'm just gonna copy-paste my response here too. The long and short is that the theory that they attacked Earth for the reasons you mention doesn't really make a whole lot of sense, at least not IMO.

"But that doesn't really make much sense. I mean, we know that the Reapers have a fairly extensive working knowledge of the galaxy, and where things are. We saw as much in ME2. Remember how the Collectors (answering directly to one of the Reapers in dark space) were going around attacking human colonies? And how they had very detailed information on numerous worlds? (That last bit is actually from ME Incursion) My point being: We know that they know plenty of locations within the galaxy, plenty of big targets. Heck, they know where the Citadel is, and that it's being used as the seat of galactic government! And remember, Vigil states that this is precisely why they normally attack the Citadel first! So positing that they're going after Earth simply because they know where it is just doesn't add up."
