Your comment made me consider something else:

If every possibility plays out in a separate universe, then the concept of choice and randomness becomes an illusion, and the multiverse as a whole can be considered predetermined, with every possible outcome already set in motion! 🫨

But... Who really knows? 🤷‍♂️ 

 Unless choices to some extent exist inside each universe and then spawns another universe with the inverse outcome.

I think then we can consider free will (randomness) to exist to some extent.

But yeah. It is not so easy to prove. 🫠
