well you dont want me giving my oppinion..... alright ill say it, by 2050, the greys ( type of alien race ) will already have came and maybe be gone, if they dont chose to stay, but thats suppose tohappen by 2017, nibiru/planet x/dark star. what some call, i call nibiru, will have already gone, nibiru is on the path of leading our solar system into the 7 years of anti-matter, 7 years of well hard to explain, but nibiru acts like a guidance, which some think nibiru is a planet for the annukis, i dont know what to believe on that, so by 2050, we will have another nut saying the world will end on another year, but our population will be cut in half cause of WW3 and galatic war with some form of alien race.
some will think i am nuts but so be it. this is my thoughts on what will happen by 2050 and i am sticking to it.
