Tolkien knew far more then he let on

Hobbits
Small people
Live in a land of giants
Slayed the beast
Sauron (eye)
Formless but attempting to gain physical form.

We are small people
There were giants before
Big Tall fookers
We slayed the beast
Eye (Betelgeuse)
Formless but attempting to gain physical form.

“Even the smallest person can change the course of the future”

We hobbits
The fate of the world rests with us.
Why us?
Why not others before?
Or others after

Not sure
Maybe this answers the questions.

If not us who?
If not know when?
