Why is the prophecy written the way it is?

No: HPFGUIDX 137892

Well, if "The one with the power to vanquish the Dark Lord approaches"
referred to the eavesdropper outside the door then the
 "Born to those who have thrice defied him
 etc" and the will be born
as the seventh month dies..." part  must also otherwise it makes no sense.

In fact, if it referred to Snape then the entire prophesy could start
and end with "The one with the power to vanquish the Dark Lord
approaches", all the rest would be meaningless blather.

And besides, it would be rather disappointing after reading 7 books
JKR laughed and said she suckered us into reading about the wrong
character, the Prophecy had nothing to do with Harry Potter and he was
of no importance.
