So, I'm going to start with the Vimanas.
In the Indian Ramayana and Mahabharata there are parts which depict in detail how to build flying interstellar crafts, among other things, like extraterrestrial races.
So, Vimanas are the mythical flying machines chronicled in these ancient Sanskrit epics of India. The story of the Vimana predates Jesus by thousands of years, and the Hindus of today’s India believe the existence and usage of Vimana to be historical fact. There is a plethora of ancient Indian literature which deals with the Vimana and its many aspects. Most of the epics await translation.
One epic, titled Manusa, gives clear instructions on how to build the craft and the proponents that make them able to fly. Other texts have names such as ‘The secret of making Planes invisible’, ‘The Secret of hearing conversations and other sounds in Enemy Aircraft’ and ‘The secret of making Planes motionless’.
There are many other texts about Vimana which are spoken of in the epics, but have not yet been discovered. Many texts speak of ships and planes with nuclear capabilities and a great nuclear war that took place. In the ancient ruins of Mohenjo-Daro, once part of the Indus Valley Civilization, 3000 year old skeletons where found with radioactivity levels that surpassed that of the bodies at Nagasaki and Hiroshima. The ruins themselves also emit high radioactivity levels. It is a documented fact that the city was destroyed suddenly.
There is also a lot of evidence out there, that in fact, Nazi Germany led by Hitler, sucseeded in creating these craft. That is just one of the reasons why there were many expeditions led by German soldiers and scientists all over the world, even in the most secluded rainforests of South America, the dessert Gobi in Asia, even the freezing Antarctica. There are rumors of German Bases there that exist to this day.
...But I will try to include more about this in the next part
