According to the timeline in the film, Paul Anderson said the attack on the Whaling Station is the first scene. However, he constantly keeps reitterating of how much he wants to hold true to the style of the first two Alien films and the first Predator. In all those movies, you never caught a full glimpse of the creature into well into the film, to help enhance the fear and build - up. In that scene under debate, if it is indeed the Whaling Station with the guy backing away, then we've already seen a Predator right at the beginning completely contradicting all that Paul has said. Also, what in the world would cause a Predator to attack a Whaling Station? That kind of defies all logic dont you think...
