Why haven t aliens come to Earth yet?

There should be aliens in the universe, but they didn't come to Earth, and there is no conclusive evidence at the moment. The existing evidence is basically spread by ** and the Internet, and it is impossible to determine whether it is reliable and true, so it is impossible to conclude that aliens have come to Earth or will come to Earth in the future. Unless** or the military officially confirms, but for some reason or it is true that aliens have not really come to Earth, so at present** and the military have never officially stated their position.

Although UFOs are common in life, most of them are misidentified by certain phenomena or objects, and basically have nothing to do with aliens, so whether there are aliens on the earth is still being explored.

How do you know that aliens haven't come to Earth yet?

Maybe they've already been here, but seeing that the Earth is too backward, and there is no potential for them to plunder or communicate here, it's not necessarily a shame to leave again.

Maybe they've been there, but seeing that the earth is so backward, it's not necessarily a shame to decide to use humans as experiments for observation.

Maybe they've already been here and think the earth is pretty good, so it's not necessarily a good idea to settle here.

Do you have to call it "coming" because billions of tens of billions of aliens are coming? Do you have to fight or make a big deal about how they have come before they are called "coming"?

Aliens have postponed their arrival on Earth until 2024.

Numerous facts have proven that the vast majority of UFOs are optical phenomena.

Again, aliens, humans have been looking for aliens and have never been confirmed.

What do you want? Don't think the earth is messy?! - Don't look for trouble?!

Hello, of course aliens have been to Earth, they have been here before the birth of humans, and they even survived for a while. Now there are many UFO incidents every year, we humans don't know what they are, and many of them have been made public, that is, alien flying saucers! Now there are aliens on Earth as well! Thank you.

At present, there is no direct proof of the existence of so-called "aliens", let alone proof that "aliens" have come to Earth.

I don't know, there are many scientists who say that aliens have been to the earth a long time ago, and some say that the earth had highly intelligent beings a long time ago, but then they became extinct.

Aliens only exist in the imagination of human beings, and there are aliens in theory, but science has also proved that due to the vastness of the universe, it is theoretically difficult for alien civilizations to reach the earth, so human beings are destined to live on isolated islands, which is the same for theoretically existing alien civilizations.

It's hard to say about luck, first you have to prove whether there are aliens, and then you have to prove whether you have been to the earth, the first is not more than the first step, and the second step is easy.

1.The greed of the earthlings makes the aliens dare not show up.

2.Aliens also want to make contact with people, but the time has not yet come.

3.Aliens think very highly of themselves and look down on earthlings.

4 Aliens are ugly and dare not appear on Earth.

5.Aliens only see Earth as a place where they can be replenished, and there is no need to appear on Earth.

6.Aliens are actually all around us, we just don't know it.

7.Aliens arriving on Earth consume a lot of energy, so they can't come often.

8.Aliens only regard the earth as a biological testing ground, they are the masters, there is no need to surrender their identities in front of us, and the call is over. The landlord chooses me!!

It's mainly a matter of the level of technology, just as humans can't reach other stars.

I think aliens exist:

Outside in the narrow sense. The height of the star is higher than that of a star other than Earth.

Intelligent life, in a broad sense.

A star man is a person who is highly intelligent from other stars.

When it comes to other planets.

Any planet that may have aliens is far away from Earth, and it will take a long time to come to Earth, and it is not very easy for technology to reach the level of interstellar travel, so it is difficult for us to see aliens.
