Why are UFOS mostly hidden by Goverments? Answer: Time Travel

The major reason that people disappear around UFO experiences is Time Travel to the past, present and future. It's really dangerous in the wrong hands. So, it's better that (though people suspect this is true) that they are NEVER Told for sure by governments what is actually going on.

For example, I know that the Galaxy uses time travel to fix things they don't like. For example, when the first timeline was ended on September 11th 2001 with 5 billion people dying in the first month after that people from 7028 on that timeline came back and created timeline two. All they had to do was to tell George W. Bush not to get angry on TV this time. So, this time he read "My Pet Goat" to the children in the class room and this prevented Doomsday weapons actually going off worldwide and ending civilization. 

It wasn't really a war at all it was a few drunk or scared people in one country or another freaking out and setting off doomsday weapons which ended human civilization for 4000 Years time until at least 6000 AD. 

Note: to be really more exact about all this we presently live on a variation of Timeline 2 which I might call either 2E or 5 depending upon how people want to designate it. 

So, you can call it the 5th variation of timeline 2 

Or you can just call it timeline 5.

It's sort of like video game software or operating system software where you might say 1.0 or 2.0 or 3.0

But, often there are other variations like 1.1 or 2.2 or 3.3 or 4.4 in operating systems.

It's all how you choose to designate something.

"A rose by any other name will smell just as sweet."

The point is when people who have had UFO experiences and need to talk or write about them they often have disappeared here in the U.S. since at least 1947 (which is also the year when the Transistor came out too which I think is interesting). 

However, people have been disappearing or worse for thousands of years speaking about their UFO experiences and often you will see this in religions past, present and future as well and even in art of many different periods worldwide.

UFOs pre-existed All Human history by the way by far. UFOs existed likely before planet earth existed if we are to be honest here.
