How to refute the non existence of aliens, has the existence of aliens been confirmed?

In fact, it's just as Capricorn said.

However, in terms of debating skills, you should avoid falling into the situation of being asked by the other party to "find evidence", because you can't find evidence, and you must not say that aliens or alien ruins have been found in a certain place on a certain day, year, month, and day. Because the other party will definitely ask you to come up with evidence, and this kind of illusory thing must not be able to produce credible evidence, and the other party will definitely be prepared in advance to refute some famous alien events.

Instead, you put your opponent in the context of "there is no other life in the entire universe". This is a sure victory.

You're going to have to grab a few points.

First, the absence of evidence does not mean that facts do not exist. Just because you can't find evidence now doesn't mean you won't find evidence in the future. The fact that the ancients could not prove that the earth revolves around the sun does not mean that this is not the case. Therefore, the absence of evidence is not a reason to refute.

Second, the universe is very large, both in time and space, and what we have explored is only a very small part. Because the places we explore do not exist, the whole universe does not exist, which is unconvincing. We stood by the sea and did not see sharks, can we say that there are no sharks in the whole ocean?

Thirdly, we are ordinary. This is a basic philosophical premise that we are born in a very ordinary place and in a very ordinary era. Unless the other party can come up with convincing evidence that we are special, we can be sure that we are ordinary.

And in fact we are also very ordinary, at least you can come up with proof of it:

Planets like the sun are everywhere.

Current observations prove that planets are very common in the universe, and although the discovered planets are too different from our earth, it can be said that the probability of the existence of planets similar to the earth is countless times greater than the estimate 30 years ago.

Water is everywhere in the universe.

The elements needed to form life are everywhere in the universe.

Simple organic matter is everywhere in the universe.

In terms of time, the earth has experienced many mass extinctions, as well as many biological flourishes. In many previous geological epochs, biodiversity surpassed that of modern times, and biological complexity surpassed modern times, such as the age of the dinosaurs. In other words, the earth actually has several opportunities to produce intelligent life, and it can also be said that a planet with the conditions may produce life more than once, or even intelligent life.

More broadly, whether it is more than 10 billion years in the past or endless years in the future, there will be countless planets born or destroyed.

Therefore, we can say that there is reason to think that there are countless planets capable of generating life, both in time and in space. Why do you think that none of them can produce life?

Logically, we have no evidence that what doesn't exist doesn't exist, and only those that already exist can find evidence of existence.

So logically speaking, neither side is a winner, we obviously can't find evidence of non-existence, and at the same time we can't find evidence of existence, the most decisive evidence of existence is, of course, to put an alien in front of everyone, but no.

However, there is only room for debate on topics where neither side is a winner.

Since there is a human being.

Then I believe that there are other intelligent beings in the boundless universe.

First of all, you have to explain that the reason why life exists on the earth is because the earth has the conditions for life to exist. Temperature, water, whatever.

Then you could say that the universe is so big that it is impossible for only the earth to be suitable for life ...

In the depths of the universe, there is likely to be extraterrestrial life ...

Earthlings can't be frogs at the bottom of the well=.=

Our galaxy is not comparable to a grain of sand in the Sahara, how can we be sure that there is no life in other sands?

Human beings are so special.

It has not been confirmed as of the end of 2019. In the past 50 years of searching, astronomers have not found any conclusive clues about aliens.

The scientific community generally believes that "life occurs only on planets around stars that emit light and heat, but not all stars necessarily have planets". Nebula theory holds that stars were formed from the contraction of a rotating primordial nebula. When contracting, due to the conservation of angular momentum.

The rotation is accelerated, and due to centrifugal force.

The nebula gradually becomes flattened.

When the core temperature reaches 7 million degrees, a thermonuclear reaction from hydrogen to helium occurs.

Stars are born. The outer part of the disk condenses into several small bodies in the process.

Sorry, the existence of aliens has not been confirmed.

Although no living planet has yet been discovered, there are some scientific studies that suggest that the possibility of extraterrestrial life exists. For example, around the end of 2020, Japan's asteroid probe Hayabusa2** returned to Earth, this time bringing back a sample of the planet's surface from a celestial body other than Earth. Later, scientists detected more than 20 amino acids from these samples, which became the world's first evidence of the possibility of extraterrestrial life.

Therefore, there is still insufficient evidence to confirm the existence of extraterrestrials. However, with the continuous advancement of science and technology and the deepening of research, perhaps more evidence will be discovered in the future, allowing us to better understand the universe and extraterrestrial life.

In the Thiaoouba Prophecy, there is a statement that we can't let the Mask Seep them know about our existence for several reasons: (at that time, the aliens Tao and Michel were "talking").

The first is for safety.

The second is the mind-to-spine level, if these people are made aware of our existence, and if they realize that we are here to help them, they will passively accept our help and take pity on themselves there, and these will weaken their desire to survive. As you say on Earth "God helps the self-helpers."

The third and final reason is the most important: the cosmic law is perfect, it works as strictly as the stars control the planets, and if you make a mistake, you will be punished - it may be immediately, it may be ten years from now, or ten centuries from now, but no matter how long it takes, you will have to pay for your mistakes. Therefore, from time to time we are allowed and even advised to help, but we must not "feed the food to the mouth".
