In Resident Evil: Extinction, how did every monument like Eiffel Tower and Statue of liberty get together here? (I think there is pyramid also on the left. Screenshot at 55:04)
This is because they were in Las Vegas, for instance, where the Sphinx and Pyramid in your screenshot is where The Luxor Hotel is.
The other landmarks can also be found in Vegas as mentioned in this website about Las Vegas strip
It is mentioned in the movie that the group needed to go to Vegas in order to get fuel to go for the trip to Alaska where it was thought to be Infection free.
Obviously these are only replicas of the real things and for the purpose of the movie production, are replicas of the replicas.
