The last day of the world we knew

Generations will be born and pass on the voyage that could mean the salvation of the entire race. The ship was automated to the point that the occupants didn't even remember they were on a ship after 200 years had passed. Now though they were within range of their destination and the ship started waking up in an effort to prepare the colony aboard for the first steps on to the new planet that would be their new home. As the ship confirmed the planet was indeed habitable and the colonists aboard start to prepare to go down to the surface billions of eyes below are locked up staring at the ship that is invading their home world.
