Here's why:
* No scientific basis: The movie's premise of a cataclysmic solar flare causing widespread destruction on Earth is not supported by scientific evidence. While solar flares are real, they are not powerful enough to cause the kind of widespread destruction portrayed in the movie.
* Misinterpretation of Mayan calendar: The movie uses the end date of the Mayan calendar, December 21, 2012, as a catalyst for the apocalypse. However, the Mayan calendar didn't actually end on that date; it simply marked the completion of a cycle.
* Exaggerated and unrealistic events: The movie portrays events that are highly improbable, such as massive earthquakes, volcanic eruptions, and tsunamis happening simultaneously across the globe.
* No credible evidence of impending apocalypse: There is no scientific or historical evidence to suggest that an apocalyptic event of this magnitude is imminent.
While the movie is entertaining, it's crucial to remember that it's a work of fiction and not a prediction of the future. The scientific community agrees that there is no reason to fear a 2012-style apocalypse.
