[Independence Day] Why do the aliens like to get the landmarks? How do they identify the landmarks?
gpt
We tend to build landmarks where we have a lot of people concentrated in a relatively small area, and where we concentrate political and economic power.  The aliens just wanted to destroy the centers of such power, and they had heckin' big bombs with which to do it.  The destruction of highly-recognizable structures was entirely incidental.
