Anime about a boy and a girl who ride ostrich-like creatures through a valley

Question

I can not remember much but I have had this film in my head for years I searched everything I can remember on every website I can think of.

I don't remember the exact story but I'll list everything about it can

• Apocalyptic future possibly
• Two main characters: a boy and a girl riding ostrich-like creatures through a valley
• An old blind lady that senses things
• Crashed spaceship looking like a submarine
• Giant creatures looks like yaks with blue eyes, whose eyes turn red when something is about to happen
• The old lady says "Some say they went to the stars" while looking at the spaceship
• The two main characters do something and their eyes turn blue in the distance and the village cheers

This film is at least ten years old and I would appreciate it so much if you knew anything about it, or could help me find the title.

Answer 1

This is Nausicaa of the Valley of the Wind.

The giant creatures with the red eyes and the submarine in the desert are a dead giveaway,.
