I believe the answer is:

creation

I'm a little stuck... Click here to teach me more about this clue!

'forming' is the definition.
(act of forming or creating something)

I don't understand how the rest of the clue works.

(Other definitions for creation that I've seen before include "Beginning event" , "work" , "Haydn oratorio" , "Reaction to act of making something new" , "Act of God" .)

I've seen this clue in The Telegraph.
