She IS an alien. Her dialogue and interludes all indicate her origin is the same as her Extella version. On Earth, she was discovered by the Huns and already possessed Photon Ray, which originally belonged to Ares, who the White Titan killed.

The material book for Extella confirms she is the same heroic spirit Altera that we see in Extella. The only difference is, the FGO version somehow lost her connection with Titan Altera, but she claims she can recall bits and pieces of memories that trace back to her origin.
