Anonymous users2024-02-03Would 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.

Anonymous users2024-01-31Because the Earth is the only planet suitable for living creatures.
Among the nine planets in the solar system, the light blue earth is the only planet full of life, and nearly two million species of life are active in its mountains, oceans, forests, blue skies, and poles, and it is a well-deserved paradise of life. But why does life love the earth so much? >>>More
For the universe, the earth we live on is just a very small existence, so to tell everyone, the earth we live in belongs to the Milky Way, and the Milky Way is only a medium galaxy in the universeThere are at least billions of such galaxies, so the earth is normal, and the special thing is that only life has been found on the earth, and people will wonder if there is only life on the earth, what is the meaning of the existence of the universe after the destruction of the earth? The universe itself is of great significance, with countless opportunities for development, and it is not as simple as we think. >>>More

The existence of life is to change the earth and maintain the earth, because if there is only the earth and no life, the earth can only exist by itself, and with the existence of life, the earth will have different possibilities.
