I'm thinking that 90% or more of people on earth have had UFO experiences

Why don't we remember these experiences more clearly?

Mostly because 60% of people couldn't handle it and might just run and jump off a cliff because it doesn't agree with their religious or philosophic beliefs and when it happened they would just have a psychotic break and be dysfunctional ever after.

So these experiences are erased by the UFOs or world government officials here on earth sort of like you see in "Men in Black" movies which are truer than you might think.

What is happening lately where Governments are talking more about UFOs?

What I believe is happening is that the human race is being allowed to thin itself out through global warming. You sort of know this is happening because when people die from weather incidents you don't see it reported on the news like you once would have. Think about what you are seeing on the major networks in the U.S. lately. All you hear about is Trump or Democratic candidates debating each other. You don't hear about the 1000 children who got Dengue fever in one day in Bangladesh for example.

So, global warming events (unless they happen in the U.S.) just aren't really being covered properly anymore where many people die.

The same thing has always been true regarding UFOs because there is a vested interest in governments and businesses to "not upset the status quo" because money might be lost.

So, people's careers are destroyed a lot (always have been) if they talk much about their real UFO experiences here on earth. It upsets the status quo so people have been killed or disappeared to silence them for at least 50 to 70 years now or maybe this goes back thousands of years more from governments not wanting to deal with the truth about anything.
