Hi from Germany!
My name is Karsten and I read the major books of Velikovsky and "The 12th Planet" by Sitchin. I also browsed in other books of Sitchin. I found Velikovsky far more convincing than Sitchin! Velikovsky was a real scientist and a friend of Einstein. You can imagine that a genius like Einstein carefully chose his friends etc. Einstein basically agreed with V that cataclysms have happened in historical times (see the book Exodus in the Old testament). Sitchin, on the other hand, was not a sumerologist and receives until today a lot of justified criticism, see for example
www.sitchiniswrong.com .
I find the subjects discussed here very fascinating! If time permits I will throw in my thoughts and opinions.
I am convinced Nibiru will visit us in a few years and cause the much prophecised Pole Shift.
Bye, Karsten
