How old can aliens live at most?

The life span of aliens is an uncertain problem.

Because we haven't been in contact with aliens, we can't know their situation. According to scientists' calculations, the life span of aliens is long or short, and the life span of aliens may reach thousands or hundreds of millions of years.

However, these calculations are only based on our knowledge and speculation about life in the known universe, and because the living environment, genetics and civilization of aliens are different from ours, their life forms and life processes may be completely different from ours. So we can't be sure whether the life span of aliens is long or short, so we can only wait for more discoveries and explorations to further understand this problem.

Maybe there are other substances in the universe that can be stored from the birth of the universe to the present, and maybe there are other lives that can survive for a long time, but aliens, Wen Mingzhen, are like this, so there must be traces of civilization everywhere in the universe, but why haven't humans found any civilization so far?

To what extent can civilization develop in 100 million years? Now, let's look at humans. It only takes a thousand years of development to go into space, and soon it will reach the level of first-class civilization, and the development of technology is constantly rapid. The technological explosion occurred under the condition of rapid development of technology. One technology can be extended to many technologies, and civilization has developed for hundreds of millions of years. It's hard to imagine reaching that level.

The discovery of aliens

Aliens are the floorboard of life beyond the earth imagined by human beings. There has always been a daydream about aliens in ancient and modern times, but now human beings can't actually detect whether there are aliens, although many people have always claimed to witness aliens visiting the earth and even contacting themselves.

However, most scholars and experts believe that the so-called different degrees of contact between humans and aliens is actually a psychological effect. The chances of humans discovering "aliens" are very small. Even if aliens are found, it is almost impossible to have any contact with them.

In the search of the past 50 years, astronomers have not found any conclusive clues about aliens. But in theory, it is almost inevitable that there are other intelligent creatures in the universe.

As of 20 15, the scientific community generally believes that "life will only appear on planets around stars that can emit light and heat, but not all stars necessarily have planets".

According to nebula theory, stars are formed by the contraction of rotating primitive nebulae. During contraction, due to the conservation of angular momentum, the rotation is accelerated, and the nebula is gradually flattened due to centrifugal force. When the central temperature reaches 7 million degrees, a thermonuclear reaction from hydrogen to helium occurs and stars are born. In this process, the outside of the disk will condense into several small celestial bodies-planets.

On September 12, 2023, local time, the Mexican Congress held the first public hearing related to "unknown anomalies", and two suspected "alien creatures" appeared.
