What do you think when Planet X / Nibiru passes?

They have tried to explain this theory in different ways, still, I think this theory does not make sense. First of all the orbit of Nibiru is something awkward, Yes, I understand that it follows the kepler's law and the concept of twin stars is also "Okay", still, if a heavily body like Nibiru enters the solar system, it will have to cross 5 planets and then it will reach near to the earth's orbit. Also, if a huge planet like Nibiru has to cross "Asteroid belt", you can imagine the result... They say, it has orbit of 3600 years, we know there is nothing in history that says something wrong has happened 3600 (or 7200) years back. Apart from this 2012 bs, this annunaki theory is very much logical. I think this is more logical than darwin theory...
