Theory #388373553668753786986214 about Tom Bombadil as a peron/being

Just jokingly somewhere (I searched I really did) is a story of Sauron's finger crawling to the old forest...

now clues we see

Sauron doesnt turn invisible with ring on
Bombadil doesnt turn invisible with ring on

Where the chopped off fingers went is never explained
(this was part of the joke but it is true)
Sauron is a Maiar so we must assume some good existed in him

This good may have basicly subsided into one of the fingers and manifested into what Tom Bombadil is today...
