Movie sounds like the Dresden code doomsday prediction.

Rating: 10/10 (4 April 2009)

The theme of the movie appears haunting analogous to the Dresden codex from the Mayan civilization. This code made between 1200 to 1250 BC appears to have various astrological predictions of various eclipses and other events that will be occurring. One notable even was a solar eclipse in July 1991 that was predicted accurately.
However, there was one weird aspect of this prediction. It was stated that a "meeting of the brethren" would be occurring on that date. On Mexico, where this eclipse occurred there was a number of UFO sitings recorded on video and observed by many eye witnesses.
This same codex has an end date of December 12, 2012. Mausumi Dikpaki, of the National Centre of Atmospheric Research (can be googled) suggests that a solar storm will occur on that year that's stronger than any other solar storms in history. Sun activity is now actually lower than usual, which she calls the eye of the storm. She predicts a 30-50% stronger solar storm than ever before. This means there is a possibility that a strong solar storm could really occur around that time as predicted by that codex.
If you were to take analogy with the movie's motif, such as the numbers on the paper in a time-capsule predicting events of the future and compare it to this codex, you add the UFO alien element, as with the 1991 solar eclipse seen over Mexico as validating the authority of predictions of this codex. Then the movie takes on a more haunting and scary tone.
The aliens in the movie are actually "Nordics". They are tall, blondish human looking people that are commonly seen in Europe. If you take all these sort of elements and make a creative work of fiction -- then you have something like this movie "Knowing".
I actually appreciated the theme of the movie and it's inspiration for me to do this private research from a tip I got watching "Mexico Roswell" from UFO files last year and looking more deeply into the Dresden codex leading into a deeply rich intellectual experience.
After doing the research, this is a brilliant fictional story, taking mythological beliefs and stories and making some sort of compilation. If you are well versed in this sort of stuff, this movie will freak you out, guaranteed. Not because of the cheesy acting through, but more what it represents.
