Intuitive researcher David Wilcock spoke about the existence of ETs, whistleblowers' testimonies, stargates, and the coming of 2012. He suggested that conditions in our galaxy have made human-type life plentiful. It's a myth that aliens are malevolent scary-looking creatures-- they actually look similar to ourselves, he said.
Much of Wilcock's material about ETs was gathered from conversations he had with whistleblowers such as 'Henry Deacon' who claims that through his work in black budget projects he met and interacted with 40-45 different human/alien species. Deacon said he traveled to a base on Mars, and there were 240,000 personnel on the Red Planet, with only 10% of them born on Earth. He also explained the ancient means of traveling through a stargate didn't permit the transfer of anything non-biological, whereas the current method allows for instantaneous travel along with non-organic objects.
Wilcock spoke about the testimony of Sgt. Clifford Stone (video interview) who said he knew of 57 different types of aliens that range from 1½ feet tall to 15 ft. tall, in every skin color including orange and green (beings from the Alpha Centauri system are said to have dark green skin and engage in a kind of photosynthesis). The ETs are particularly focused on Earth, as we are about to go through an energetic change in 2012 that will raise our frequency to their level, Wilcock explained.
