Why Earth is the only planet in the universe where life exists

Would you believe it? Humanity is the first civilization in the universe! This is not credible for us, because we really have no way to prove it now, because the other civilizations on our team have explored for so long and still found nothing, which has to make us doubt whether the other civilizations on our team exist.

We already know a lot about our own human civilization, in fact, we can't say that we understand it completely, after all, human beings are constantly evolving, and there are many mysteries on human beings that we still can't solve, and the mystery that bothers us the most is that we come from ** to **? From this question, we also reflect a greater desire to know about civilizations other than our human civilization. <>

Since our technology can allow us to launch satellites and probes, our human exploration of space has not stopped for a moment, this is a grand and long-term project for us, and we scientists are not particularly confident in the results behind this project, because until now all our probes have not directly explored strong evidence to prove the existence of extraterrestrial civilizations, and we have no clue about it.

Why is it possible that human beings were the first civilization in the universe? We can analyze from the current situation, if human beings are not the first civilization, then there must be other civilizations that are more developed than our human civilization, then it is very likely that they have come to our earth, but why have we not been able to find out, or why have they not made contact with us? This is a very big doubt.

And if there are other civilizations, will we humans be safe in the end? Because the resources in the universe are finite, why don't they look for them where we can see them? We don't know about that.

There are too many secrets that we can't understand, so that we are now doubting the existence of extraterrestrial civilizations, after all, when our scientists are looking for extraterrestrial civilizations, they are still looking for them according to the situation of our earthlings, which shows a truth, don't scientists know that extraterrestrial civilizations are different from us humans? They must know, but they are not sure if there is, or our human civilization is the existence of the first civilization in the universe, which is very difficult for us human beings to find us from ** to **, which also indirectly shows that our human civilization is very likely to have no pre-history in the universe, which means that human civilization is likely to be the first civilization in the universe. <>

Do you doubt that human civilization is the first civilization when you hear this news, yes, everyone will doubt it, but after all, we don't have the strength to find evidence of the existence of other civilizations, if we want to understand everything, then we must work hard to develop our technology and strive to clear the clouds as soon as possible.

Because only the Earth has the conditions necessary for the survival of life: stable solar light conditions;

Relatively safe.

Cosmic environment. Because the distance between the sun and the earth is moderate, the surface temperature is suitable (the average temperature is 15 degrees);

Because of the moderate mass and volume of the earth, the earth can attract the atmosphere to form an atmosphere (mainly nitrogen and oxygen);

Formed and present.

Liquid water.

Because only there is water on the earth, and water provides the conditions for the origin of life, there is life on the earth, and there is no life on other planets in the universe.

Because the Earth is the only planet suitable for living creatures.

Mankind's exploration of extraterrestrial life has never stopped. Since the beginning of space exploration in the last century, a large number of probes have flown out of the earth to explore celestial bodies in the solar system. Unfortunately, of all the celestial bodies we have explored, life has not been found on any planet.

We have to admit that the Earth is the only planet we know is alive. There is a good chance that we are the only ones in the universe. However, many scientists have put forward different opinions, arguing that the form of life cannot be narrowly defined in terms of life on Earth.

Most of life on Earth needs oxygen and water to survive. These organisms that use carbon as the basis of organic matter are collectively referred to as carbon-based life, which is the life form we know. However, the universe is so beautiful, will there be life on other planets and even other galaxies that are completely different from Earth?

The diversity of life forms should be a universal phenomenon in the universe. Perhaps there is a life in the depths of the starry sky that does not need water, and they survive on hydrogen. Some scientists speculate that there may be life in the form of energy in the universe, or life in the form of information.

But all of this is just speculation. The life we currently know can only look for whether the life that exists in the theory really exists according to the life forms on the earth, and we have no way of knowing whether there are other forms of life. In the vast universe, the earth may not be the only life, but intelligent life is a very rare species in the universe.

The earth began to evolve life billions of years ago, and it has to be said that human beings were able to evolve into intelligent life and then create a new civilization, which has to be said to be a miracle in the universe. Dinosaurs ruled the earth for 1.6 billion years without being created, and civilization can be imagined, and the evolution of intelligent life is a probability event. Although we have flown out of the narrow solar system, we know too little about the real vastness of the starry sky.

Whether there are other types of life in the universe, human scientists have been trying to find out, and perhaps in that distant deep space, some more powerful life forms than us are watching us. Just as we look at ants.
