A large alien structure lands on earth, very similar to the movie Arrival but it is not. There is only one alien inside, and I believe that a woman is the main character, and is the one that “speaks” with the alien. I feel like the main character might have had a daughter (unsure.) I do not believe the alien or structure was hostile, but I do remember a scene where the military attempts to blow it up, and nothing works against it.
This is very unsure, but I believe it is somewhat of a love story near the end, and the alien sacrifices itself for the woman?
This question has been bothering me forever and I cannot find the answer online.
The Day the Earth Stood Still, maybe. There’s a newer one with Keanu Reeves that was based on an older version.
Maybe one of the “Epoch” movies:
