Has NASA discovered Nibiru?

I have received a number of requests from people who are worried about Nibiru, the planet that is supposed to demolition earth on December 21, 2012. The worried people site a YouTube video as their proof. The video, which I have seen, says that it is made by a NASA scientist ,who is afraid of death or dismissal for revealing the truth – that NASA is keeping secret from the public – that NASA is tracking Nibiru.

I find it challenging that although intelligent people can tell that the special effects on a commercial movie such as, say, the Star Wars series, are fiction but they cannot extrapolate that someone could use computer software to make a movie on their home computer or laptop and post it on, say, YouTube. I feel sad that some intelligent people don’t consider that this homemade video could also fiction – merely a creation of some person’s mind. And that that person could say they are a NASA scientist or anything else that person wants to say … but it could all be fiction.

I find it challenging that just because someone sees a YouTube video they automatically assume it must be the truth.
