Start with one asset you do yourself. They chose the spaceship. All the resources go into the spaceship, its animation, design, etc. Everything else is just an excuse to have a spaceship.
The pylon might have come from Turbosquid. There are car models, but these guys modeled and composed their own VW, possibly from an earlier exercise.
The whole environment is done in e-on vue. It's really fast and easy to get a realistic environment, for a big penalty in rendering time and flexibility, artistic and editorial.
The sky they chose, the Sunset, is probably e-on vue's most popular preset. Here are some more examples. [0][1] It's one of the few skies that gives you dramatic lighting. But it's given away in this movie, Cloud Atlas and Life of Pi (both of which used vue and this preset, hilariously) by its extreme orange saturation. [2][3]
Like software development, CG is often about finding the right bits and pieces and putting them together.

Apparently the 39 second UFO clip took a team 4 months.[1] Not so fast?
