1. Reclaimer doesn't necessarily mean that you owned the thing in the first place. For example a scrap merchant can reclaim a piece of furniture from a dump. They didn't own it, but they reclaimed it. So it can simply mean "To bring an object back to it's proper use."
2. The Monitor told the Prophets that only Reclaimers can activate the Halos. So Tartarus got a recalimer to activate them.
To your first and second points, you are not neccesarily correct, since in Halo: The Flood, when MC and 343 GS are in the control room in Halo 1, 343 GS says to MC, "Last time YOU asked me: If it were my choice would I do it." The Monitor Continued, " Having considerable time to ponder you query, my answer has not changed." He specifically refered to MC as a Forunner, because why would the Forunner have him call them Reclaimer when there hasn't been anything to reclaim yet.
3. The forerunner left lots of stuff on lots of different planets. We don't know that that object is the Ark (although it probably is). Even then, Earth is as good a planet as any other. it just so happens that it's on earth.
To your third point, yes, the Forunner created lots of objects on other planets, but it just kinda seems suspisious that the Ark happens to be on Earth. And we do know it is the ark because Bungie has said it was.
Personally i think when Cortana says "I know you, your past your future". She is talking directly to the chief.. as in "I know when you come from. That you were made to fight. That you'll do whatevers necessary to protect humanity. That you'll destroy the ark and yourself if you think it'll save lives."
Yes, well I said this is only a theory, and that is something I just thought of.
And I do hope the Humans are the Forunner, because I think they could make an interesting twist in the story from it.
