The UFO cover up is immense, and my guess is that everything else that we are told to be 'concerned' about is nothing more than a diversion.
That ET is here, and has been for a very long time, is known. As to why we are led down this path of having to hear an 'expert' or a 'politician' announce that they are here is the real thing that should concern us. Every 'expert' that is wheeled out on the media has never seen a UFO, or ET, and has no evidence to support their existence. What they all do to a man is sow the seeds of doubt. Ask yourself why this is? Anyone who is prepared to step forward and provide witness testimony is completely ignored, and if they do open their mouths they are ridiculed. This is universal, and cannot be a coincidence. Now ask yourself why a UFO 'expert' is described as such when they appear on the media? They are not experts in anything at all.
During my lifetime, and I am now over 60, as well as teetotal, a string of business qualifications, programmer, project manager etc etc, I have come across the following:
1. RAF pilots telling me that they are regularly sent up to intercept UFO's, but can't get near them.
2. An RAF junior, who was at a UK airbase which was placed on lockdown one evening decades ago. He and a friend went outside for a smoke. A craft came down to the runway and stopped dead, hovering off the ground. The pilot disembarked but was not wearing a standard uniform, he was wearing some kind of head to foot gown.
3. Absolutely true, my own experience. Around ten years ago I was stood on my back step one November night around 11pm, having a smoke. Out of the corner of my eye I glimpsed something small and black fly under a street light and disappear behind my garden wall. While I was wondering if I imagined it, this black object rose up from behind the wall, and flew right up to my nose. No inertia, no noise, no flashing lights, it changed direction through 90 degrees without slowing down. When it was 2" from my nose I could see it clearly. About the size of a video cassette, but although box shaped it has no edges, the inside and the surface can only be described as a constantly moving and illuminated plasma type material, in green, grey and black. It simply flew up to me, and then rose vertically into the darkness and over the roof of my house in one flawless movement. One of these could be behind anyone and they would never know it was there.
4. The abduction tales need thinking about. Look at the missing people statistics for all countries. Tens of thousands go missing every year. In the UK no one can go missing unless they are murdered and buried. The second anyone takes a job their NI number is required, so at that point they are not missing. Say 20,000 go missing every year. Over 20 years that is 400,000 people. If they had been murdered we would be knee deep in dead bodies by now, but we aren't, so where are they? No one is looking for them, no one is raising the disappearance of 400,000 people? What do we get? Huge resources and publicity regarding the disappearance of one girl in Portugal. Now look at the global figures for missing people.
Don't be led off the path by subtle road signs placed there by the media. They do it all the time, and 99% of the time it works very well for them. When they point you in one direction, start looking in the opposite one.
I can highly recommend the Newearth channel on YT, the team has travelled the globe finding the ancient megaliths. The truth is blatant, it is there to see, these colossal monuments both above and below ground could not have been created by a bunch of primitives.
Search for Mars on YT, or Neville Thompson Gigapans on Google, the pics you see in the press are low res panoramic shots. Download the TIFF files from NASA and zoom in 200%. The surface is littered with engineered parts, buildings and vehicles. Anything that is too obvious is covered with NASA's magic sand, or recently their new magic gravel. This is a good one. The dark side of the moon has some incredible structures.
