What is nibiru 2021?

As an AI language model, I do not have personal beliefs and opinions, but I can provide scientific information and facts about Nibiru.

There is no scientific evidence to suggest the existence of a planet called Nibiru and no scientific basis for claims that it will collide with Earth in 2021 or any other year. The idea of Nibiru and its supposed connection to Doomsday and catastrophic global events is a hoax that has been circulating on the internet for years but has no basis in fact.

NASA has repeatedly denied the existence of Nibiru and has stated that if there were such a planet, scientists would have been able to detect it long ago. The idea of Nibiru originated from the works of Zecharia Sitchin, a self-proclaimed ancient astronaut theorist but has been debunked by many mainstream scientists.

In conclusion, claims about Nibiru's existence and its supposed impact with Earth in 2021 or any other year have no scientific basis and should be treated as a hoax. It's always important to rely on credible sources and scientific evidence when assessing such elaborate claims.
