Another Theory

This theory is hot off the presses, so to speak. In other words, I just thought of it while I was sitting here.

Why did Dumbledore have the cloak, when he could become invisible without it?

He wrote to Harry, "Your father left this with me before he died. Use it well."

During JK's chat with Melissa and Emerson, Melissa asked the question: "Was anyone else present in Godric's Hollow the night Harry's parents were killed?"

JK: "No comment."

Now, she says on her site that Snape was not at Godric's Hollow that night.

THE THEORY

I propose that James/Lily had Peter write their 'address' on some paper, and got this paper to Dumbledore, in some fashion. Maybe Sirius delivered it, which could canonically exonerate Dumbledore from the culpability of blaming Sirius for betraying them.

For some reason, Dumbledore was at Godric's Hollow. I suppose arguing with them, although I do not see what it was about. Possibly to try to get them to move again, or something. I also think that perhaps they thought they knew better than he on how to deal with the whole Voldemort/prophecy threat. Perhaps he hadn't told them the whole prophecy either. (?)I realize that the "why" of this is full of holes. *shrug*

The important thing is... he was there.. and for "insert reason".... Lily petrified him. While he was sitting/standing there.. Voldemort started to break in, and James tossed the invisibility cloak over him. He was forced to watch/hear the battle, and the death of James. Then the death of Lily. Which freed him from being petrified. Voldy cursed Harry and vanished before Dumbledore got there..

OK... next part is just crazy, if you love Dumbledore. But if you think him manipulative.. well.. ....

In a fit of pique, he blew their house apart, not unlike Harry did to his office. Then, Harry being knocked unconscious by that curse, and Dumbledore, lost in his grief, expected him dead.... I dunno.. he just left to go get drunk.. ran into Hagrid in a bar... (not really).. taught Hagrid to read, which took better part of a day.. and then drunkenly told Hagrid he might as well go get Harry.. (insert reason). Hagrid got there.. Sirius showed up.. Hagrid took Harry and the bike, after knocking Sirius out.. or egging him on to go find Pettigrew..

Say.. that brings up another point. If Hagrid knew anything.. and we know Pettigrew somehow told him where Godric's Hollow was (Hagrid having nicked the paper from drunk Dumbledore).. if Hagrid thought Sirius was the secret-keeper, why didn't he do anything to him? *shakes head*

I guess, if Hagrid is evil, he could have egged Sirius on to go get Pettigrew, and then left him to rot, cuz he (Hagrid) is a rotter.

Ok.. but the point I want to make.. is that I think the person under the cloak at Godric's Hollow was Dumbledore, and when Lily died, and the petrification lifted, he fell, cutting his knee into the shape of the London Underground.
