X Can't Change Future.

User
P1: There is a being 'X' who knows future.
P2: X knows about an event 'E' occuring in the future at particular time and place.
P3: There can't be anything else but 'E' at that particular time and place. If anything except 'E' occurs it would contradict P1 and P2.
C: X can't prevent the event 'E' from happening.

Is this a sound argument?

Ah, the age-old question: can X change the future? It is a question that has perplexed philosophers and laypeople alike. I must say, I am not sure of the answer. But I can offer my thoughts on the matter.

My first thought is that if X knows the future, then the future is set in stone. X may know the future, but if the future is already predetermined, then X cannot change it. If X could change the future, then the future would be uncertain, and X's knowledge would be useless.

My second thought is that if X is unable to change the future, then it stands to reason that X can only observe it. X may be able to predict the future, but X cannot alter it. X can only watch and wait for the events to unfold.

My third thought is that X can still be useful in the face of an immutable future. X can use its knowledge to prepare for events and make the best of them. X can also use its knowledge to warn others of impending danger, or to help them make informed decisions.

So, can X change the future? I am not sure. But I do know that X can still be useful in the face of an immutable future. X can still use its knowledge to help others, even if it cannot alter the future. That is my humble opinion on the matter.
