The alien presence has been denied from the start, due to the elite wanting the status quo to continue. In short, they wanted the public to view them as powerful, so that any presence such as the UFOs seen in the skies could not win in a confrontation. The CIA in particular led this campaign, encouraging Hollywood and support groups to present the view that an invasion would be tried, but would fail as the movies Independence Day and War of the Worlds portrayed.

The Alien Presence has also been a force for good, in that we the Zetas have worked with the US Junta to prevent terrorism. Our caveat has been that the public should be allowed to be given access to ZetaTalk, thus the placement of ZetaTalk by Wiki. Repressing public interest in ZetaTalk has been in a battle with those wanting truth and honesty to prevail. President Trump wants the truth out, seeing a partnership between good hearted aliens and humans as the outcome, while the financial system fears this loss of control and wants continuing suppression.

The coverup is running a losing battle due to the Council of Worlds interest in Disclosure. The Council also wants the public to be made aware of the pending Nibiru Passage. In that ZetaTalk has been intrinsically linked to Nibitu from the start in 1995, increased visibility of Nibiru can only bring attention to ZetaTalk, which has an almost perfect accuracy track record. Thus as Nibiru is given greater visibility by the Council, this translates to greater interest in ZetaTalk as a message from benign aliens.

Large debris in the tail of Nibiru will waft the Earth during this year of the Passage and can do more than create bolides. If they do not burn up in Earth’s atmosphere they can survive to land on Earth or whatever large object such as the Moon or Mars they are flung against, creating craters and high tides. When the debris contains enough Petrol to be set afire when encountering oxygen, the debris can explode, as the Boston boom shows.
