The whole thing is a scam, just to freak people out. No one knows when the world will end. Only God knows. He decides our fate. Not us. People just need to get that through their heads.
The meteor that hit Houston, Texas was just part of the Geminids, Meteor shower, which is normal to happen and more common than you think. Each year, there will be a Meteor shower, similar to the one that happened on December 7, 2012. It's not a sign of the end of the world. It's normal. NASA even confirmed it as one of our regular Meteor showers. The Meteorites pass through the Asteroid Belt, which enables us to see them. Then, the Meteorites form into little pieces of rock; causing debris to fall down on Earth.
The thing about NASA is... the government's kind of behind the whole thing. NASA listens to what the government orders them to do. So, if it was to say that the end of the world was coming near, NASA would respect that and say that, but sometimes NASA doesn't respect those kinds of orders, because they know it's wrong to send people into that kind of panic.
There?s no point in acting surprised about it. All the planning charts and demolition orders have been on display at your local planning department in Alpha Centauri for 50 of your Earth years, so you?ve had plenty of time to lodge any formal complaint and it?s far too late to start making a fuss about it now. ? What do you mean you?ve never been to Alpha Centauri? Oh, for heaven?s sake, mankind, it?s only four light years away, you know. I?m sorry, but if you can?t be bothered to take an interest in local affairs, that?s your own lookout. Energize the demolition beams.? ?

He suddenly lunged across the chamber at something behind Arthur's line of vision. "What's this switch?" he cried. "What? Where?" cried Arthur, twisting round. "No, I was only fooling," said Ford, "we are going to die after all.? ? Douglas Adams, The Hitchhiker's Guide to the Galaxy - All through my life I've had this strange unaccountable feeling that something was going on in the world, something big, even sinister, and no one would tell me what it was." "No," said the old man, "that's just perfectly normal paranoia. Everyone in the Universe has that.? ? Douglas Adams, The Hitchhiker's Guide to the Galaxy - ?I don't want to die now!" he yelled. "I've still got a headache! I don't want to go to heaven with a headache, I'd be all cross and wouldn't enjoy it!? ? Douglas Adams, The Hitchhiker's Guide to the Galaxy - Don't Panic.? ?
