There just as much completely unrelated to the incident in that as there is related.

Also, what guarantee is there that whomever created that document didn't just date it two days prior to acquire more funding for doing spooky things?

I don't think there's a "guarantee" that it wasn't backdated, but there isn't any evidence of that either.

Since backdating would be one of the ways to fake this, the onus lies in those that claim the prediction was legit.

That's how evidence works for extraordinary claims. Alas, scientific rigor is a harsh master.
