People are saying that The Pillars Of Creation have been destroyed, and will take 400-500 Million light years to reach us. Can someone explain how do we know it when the light hasn’t reached us?

If you saw a 100 year old picture of a middle aged man you could say with absolutely certainty that he’s dead, right? The same logic applies. That kind of celestial phenomenon has a certain life span and it’s shorter than 400 million years. Therefore we know its something very different now.
