If you can't read the music itself, then learning will take time.
If you want to learn creed quickly, you should learn the Tabs.
What tabs are are bars underneath all the ledgers of notes that represent each string. Those bars will have numbers on them that tell you where to fret in order to play the song.
If you dont have the books with the Tabs in them, then go to
www.mxtabs.net and into the guitar section, then click C, then go to creed, it will list all the songs there. The more stars it has after you click it the more accurate it is (most of the time).
