Because we have been the direct object of genetic tampering by many extraterrestrial visitors throughout history, we now contain DNA from over 20 extraterrestrial species but this have done us more harm then good. Besides our short life we are more receptive for diseases, and we have a limited consciousness.
The closest humanoids in space are the Venusians. Just as all other planets, Venus is hollow on the inside. A human civilization lives there which has already developed itself to the fifth dimension. Venusians have the same origins as we do (the Vega constellation) and therefore feel very involved with us. In order to visit Earth they have to lower their vibration, and then they look nearly exactly like us.
“The landing of Valiant Thor was perhaps the first documented landing of a human-type alien by military officials. He met with President Eisenhower and Vice President Richard Nixon for an hour, then the alien was put on VIP status and shuttled back to the Pentagon.” –Harley Byrd, Project Blue Book, United States Air Force.
Thor lands on Earth on March 16th, 1957, and lives at the Pentagon for 3 years under the Eisenhower Administration.
And obviously he was not the only one!
