Thank you so much! I love how you interpret the scene. It is not like the alien race is able to predict the future though. My idea was: They observed the earth the whole time, thus, knew humanity built a laser for shooting them. But they are able to 'watch' in real-time due to some very advanced technology. This way they just waited for humans to fire the laser and immediately revealed their ship. So..For the aliens everything happens in real-time, while for humanity everything is 5 seconds too late :D
