Will aliens come to destroy Earth?

I haven't seen them do anything bad anyway.

In many sci-fi blockbusters, there will be scenes of aliens invading the earth. In those frames, the aliens look invincible, they possess a powerful ** and can burst out with huge energy. While human beings enjoy the visual impact, they can't help but wonder why in many science fiction films, human beings can't live in peace with aliens.

But if the element of "aliens" is added to the film, mankind will face endless disasters. So much so that after watching the movie, people wondered why aliens would invade the earth?

We can analyze it in detail, there is definitely more energy in the universe than on the earth, and in the Marvel series of movies, we can see that the hardest metal on the earth is just a pile of broken copper and scrap metal in the universe. We can see that Iron Man looks powerless in front of Thanos. If the planet's energy and resources are so fragile, why do they want to rule the planet all the time?

In fact, it all could be about humans. The earth is similar to dust in the universe, such an inconspicuous existence, but it has given birth to a large number of species, one of which has actually created civilization. That's right, this species is human.

With our own inventions, we began to leave the earth and go into outer space. This attracted the attention of the creatures that lived there, and they came to Earth urgently. What conditions would be needed if aliens invaded Earth?

In this regard, scientists said that if aliens really exist, they may need four conditions to invade the earth. The first is that their level should not be too high, and if their level is too high, the conditions required will naturally be very different from those of humans. According to preliminary estimates, the two civilizations are within 2-3 levels, which is the best level difference.

In this case, an alien invasion is most likely. The second condition is that it is similar to humans, and as carbon-based lifeforms, human beings have very special conditions for survival. The environment of the earth is the most suitable for us to survive, and if aliens want to come to the earth, they must change their body structure.

The third condition is that its target must be precise, and this condition is easier to understand. According to the current level of human civilization, we are generally relatively friendly when we discover other civilizations. If they are hostile, they will only be greeted with "shotguns".

Extraterrestrial beings must have a strong will and a precise goal to survive on Earth.

The fourth condition is that the location from the Earth is suitable, and humans are limited by the distance and cannot explore certain planets. The same is true for aliens, the only difference between the two is the speed of the vehicle. If their starting point is too far from Earth, the danger they encounter will inevitably increase, and they may disappear before they reach Earth.

No. Because aliens are supposed to cherish life very much and will be very friendly, they will not invade the earth.

Not necessarily, because the living environment and food of aliens are not necessarily available on Earth, and it is useless for them to invade.

Possible invasion of the Earth. Because the resources of one planet are finite, once depleted, they may plunder the resources of other planets.
