Why do so many people not believe in the existence of UFOs and aliens?

Seeing is believing, if you want people to believe in UFOs or aliens, unless you capture an alien alive and announce it, you can believe it after showing the spacecraft, and it is impossible to capture aliens alive with current technology unless it is a corpse, because the alien civilization that can reach the earth must be thousands of times higher than the civilization of the earthlings. But I believe that there are aliens, and there are countless stars in the universe. How can there be an earth of its own in 100,000 miles, but the current space technology is super backward and the speed is very slow.

We can't do cosmic sightseeing, so it's still a mystery if there are aliens, maybe it's not a mystery to aliens anymore, and maybe we have us on their TV. It is said that this is the ancient people who are tens of thousands of years behind us. When the IQ of human beings reaches 100 million times that of the current IQ, they may dominate the universe.

I believe that people must be able to figure out all the mysteries, but I really don't understand how to invent a time machine, and go back to that time to see.

In the past 100 years, human technology has developed at the speed of light, and UFOs have continued to appear, which is questionable. I really don't believe that those high-tech technologies were invented by human beings, who is so great? Nuclear, nano, space, genetic, molecule, computer, complex program, multi** electromagnetic waves.

My own view is that for the last 100 years, UFOs have discovered the Earth and worked with heads of state to make it public, but they haven't made it public, lest it cause an overreaction from the public, or leak out the technology of cooperation.

Many people see UFOs, it should be UFOs and military and political cooperation in various countries UFOs want to be extremely hidden, and when they are returned, they are still accidentally discovered by humans.

No information has been released on the UFO incident. It seems to be mysterious...

Human civilization has been around for thousands of years, and there have been no high-tech and UFO events for thousands of years, but now UFOs and those high-tech are gushing out like springs, is it just a coincidence?

Are the more than 100,000 UFO sightings on Earth just a hype of some psychopath?

Hey, I'll tell you, if there is a UFO, the military will secretly study it, and not publicly report on the UFO incident is the highest level of secret.

What you see now and what the military knows about it has long been known about the UFO incident.

It's the superlative, and ordinary people would never think of it, and they can't see it.

If the universe is so big, it's weird that there are only earthlings, it's a waste of space, human beings, wake up, don't think that there are only earthlings in the universe. That's impossible.

The fact that aliens exist is just that ordinary people don't know about it.

Human beings prefer to believe that they are the highest beings rather than see more advanced beings than themselves, but they are simply deceiving themselves.

I believe! If you think that the universe is so big, what evidence is there that there is no UFO? Besides, there are so many facts in front of you, all of them are witnesses to UFO incidents, are they all fake?!

Lack of authority, human civilization, scientific development is limited, but I believe that human beings will one day figure everything out.

Because they haven't seen them very materialistic.

There is no scientific basis, and there is no artificial satellite in any corner of the earth...

I'm sure I've seen the true face of UFOs and the wreckage of aliens in a book.

Without evidence, it is not convincing.

So who knows you, you know?

Why can't we see aliens (clipping out the illegal souls, reincarnating words, aliens playing mosaics, etc.).
