There are many things that we just listen to others say, watch others confirm, and then believe others. Have you ever thought about what you think? Does the earth have to be solid? Not necessarily, are there only humans on earth? Not necessarily. Is there no way for us humans to go to other planets? Not necessarily, why are there so many uncertain answers? Because no one can give an example to show that this is wrong.
When you open your eyes again and find that the world has changed drastically, and everything that was impossible has happened, will the world still be peaceful? Can people or people or other living things coexist peacefully?
Purpose: A world with excessive technology may not be the world we want. Human nature is selfish and terrible.
