Think about it, if an alien came to Earth, what would be the first thing he would say?

They will say, "There really are aliens."

Not necessarily. Depending on their size, if they are stronger than humans, they may destroy humans.

Probably won't be any better, right? After all, we live on different planets, and they are just curious about our lives and politely come to visit. Let's see if there are any resources to share next.

It can only be said that people sit at home, the pot comes from the sky, and the aliens come to the earth to prove that the earth is theirs, and they just want to take back the earth, what should humans do? "Cheating"? Probably not, since aliens have the ability to travel stars, the level of science and technology must far exceed that of human beings, and even reach the level of second-level civilizations, they want the earth, and human beings can hardly resist.

It may also be that our thinking logic now can't imagine what kind of mood we felt at the moment we saw them.

For me, I was pleasantly surprised, but not surprised. Growing up, I have always believed that we are not alone in the vast universe. There are higher civilizations, and there are so many more that we don't know.

If they really come, then it is a civilization that is higher than ours, higher than our technology it is inevitable. Such an advanced civilization no longer needs any resources on the earth, and it is better to enslave us than to rely on machines or unexpected technology.

What would we have done if Earth had discovered a smart planet not far away light years away, 500 years below our technology?

For example, tomorrow aliens will jump through time and space, wormhole technology, faster-than-light flight, suddenly appear, and there will be a war, what do you think we can do, what is the difference between this and people digging an ant's nest, what can we resist Using a nuclear bomb is not much different from a bee stinging, for aliens who come from thousands of miles away.

Of course, it is possible not to fight and help us improve science and technology. But if we want to join the Star Alliance, do some small business, and pay taxes every year, we can be protected, do you dare not agree.

Don't think about resisting, only the mentality of treating aliens as immortals is the right choice. Because since the aliens can come to the earth, it shows that the level of science and technology is much higher than that of the earth, and human beings have no chance to resist, only pray and repent that the aliens are goodwill visits, unlike human beings who plunder and kill when they discover the new continent.

You can eat and taste it, and you can play for a while. It's good to talk about it, and if you can't beat it, you can dodge.

Extraterrestrial civilizations must existHuman beings have lived on the earth for tens of thousands of years, but the time for the birth of human civilization is only a few thousand years, and such time is just a drop in the ocean in the entire universe. There are countless stars and countless planets in the entire galaxy, although it is better to have planets that are as suitable for life production as the earth, but the number of planets in the entire universe is too large, and there are countless planets that meet these conditions, so these planets will definitely give birth to life, and it is very likely that they have developed into extraterrestrial civilizations, just because human civilization is too far away from them to be discovered, and it is also possible that alien civilizations do not let humans discover them. <>

Extraterrestrial civilizations don't have to be friendlyIn the famous science fiction ** "The Three-Body Problem", there is a cosmic law of the dark forest, that is to say, the universe is like a dark forest, every civilization is a hunter with a gun, as long as other civilizations are found, they will shoot them, because other civilizations in the universe are a threat to high-level civilizations, if they are allowed to develop, they are likely to become the fierce enemies of their own civilizations in the future, so every civilization in the universe is trying their best to hide themselves, I think this law is very likely to be correct, And human civilization is still looking for extraterrestrial civilizations in the universe in a high-profile manner, which can be seen to be very dangerous. <>

There is a high probability that an extraterrestrial civilization will be harmful to EarthExtraterrestrial civilizations are likely to cause harm to Earth, and even the entire solar system. Because not every alien civilization is well-intentioned, they will not selflessly help the development of low-level civilizations, the Indian civilization has developed to a certain height, resources are the only goal, and the purpose of alien civilizations coming to the solar system should be for the resources of the entire galaxy, or even to seize the energy of the stellar sun, so if the alien civilization comes to the earth, then human beings have no strength to resist at all, only to be destroyed by alien civilizations, and human beings are still looking for alien civilizations in the universe. It can be seen that it is very dangerous. <>

I don't think it will be harmful to the earth, because the aliens' technological level has reached the level of interstellar civilization, which is equivalent to god-like existence, and the resources on the earth are very barren for them.

I think that if aliens come to our earth, it will also cause some harm, after all, their technology is still relatively developed.

I think it's going to be harmful, because there's a good chance that aliens are coming to invade our planet, and they're probably smarter than we are.
