Since the universe was born at a singularity
I believe we are all familiar with the "big bang theory of the universe", after all, this is the mainstream theory to explain the origin of the universe, we usually understand the theory that the universe was born in a very small, very dense, extremely high-temperature singularity, about 13.8 billion years ago, this singularity exploded, and then gradually evolved into what we now The universe as we see it now. But the question is, since the universe was born in a singularity, what is outside the singularity?

Advanced civilization of 1 billion years level
The scientific community generally believes that the universe was born about 13.8 billion years ago, and according to scientists' estimates, rocky planets were already prevalent in the universe about 10 billion years ago. As we all know, the Earth is a rocky planet, but the Earth is lucky to have a series of natural conditions favorable to life, because of this, life on the Earth can live and eventually evolve into human civilization.

Let's talk about this topic.
