Prometheus, for one, to dispense with God? (4-5)

I believe the answer is:

fire-maker

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

'prometheus for one' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'dispense with god?' is the wordplay.
'dispense with' becomes 'fire' (I can't explain this - if you can you should believe this answer much more).
'god?' becomes 'maker' (as in meeting one's maker).
'fire'+'maker'='FIRE-MAKER'

'to' is the link.

Can you help me to learn more?
