Resolving copies of permanent spells become tokens as they enter the battlefield. These tokens are not considered "created" when this happens.

If you cast a spell with demonstrate and both you and an opponent copy it, the opponent's copy will resolve first, then your copy will resolve, and finally the original spell will resolve.

You choose whether to make a copy as the demonstrate ability resolves. This happens before the original spell resolves. Your copy goes on the stack above the original spell.
