The world beyond the earth is unknown. Is it necessary for us to continue exploring?

The surface explored by human beings. Marine humans have not explored it yet. Half of the oceans have not been completely explored by human beings. Not to mention there are many trenches. I don't know what percentage is left. This is the center of the earth. Which is the mantle region. We all know what crust is. But when we reached the mantle, no one went down. Not to mention the lower mantle, and then there is a deeper layer. So people in the inner earth don't.

Is the earth also an enlarged version of Easter Island? Are we alone in the universe? Are our natural resources limited? Can we exchange resources with other planets? What we can use now is actually the earth, and the visible future is the solar system. If we have the ability to exchange resources with other planets in the future, will other civilizations be equally lucky?

To put it bluntly, don't be too conceited Perhaps, we humans just haven't touched the ceiling of our own development, and the resources of the earth are enough for us to squander. The problem is that we haven't gone out yet. Why does everyone have the illusion that human beings can definitely go out? In the past 400 years, the human earth has developed rapidly and satellites have been launched, so I feel that nothing can trap people in another 400 years. It's like a person who spent three days studying and got 60 points, thinking that he can get full marks after two days of review. Take too many clothes. The nearest galaxy is also measured in light years.

Before we immigrated to Mars, we were locked by the earth. We were locked in the solar system before we left it.

If one day we go out and find other civilizations trapped on our native planet, is it so strange? It is also possible that the civilization on their planet locked itself in a locked state of development before discovering the control of resources.

There is a pessimistic view that there are all kinds of civilizations in the universe, but they are all locked up by the "geographical location" of their own planet, and even the degree of civilization stays at a very low level. Personally, I don't think it's necessary to be blindly optimistic before mankind walks out of the solar system.
