Which planet will humans move to in the future?

According to the current scientific exploration, the upper atmosphere of Venus is similar to that of the Earth in terms of pressure, temperature and gravity. Even if there are carbon dioxide and sulfur dioxide, they can only float in the air, so it is difficult to use the ground resources of Venus. I'm not sure whether humans can overcome it in the future.

In addition, Uranus can also be used as an alternative. Because the upper atmosphere of Uranus is rich in water, organic matter, nitrogen (ammonia) and other substances needed for life, the air pressure is the same as the sea level of the earth. Gravity is even slightly lower than that of the earth, and deuterium and helium 3 can be extracted as nuclear fusion fuels. But it's too far away, too cold and windy, and Uranus' rotation axis will also bring problems to day and night and seasonal changes.

In fact, living on a planet is just a primitive idea, and the best way is to live in a giant spaceship.

Benefits:

1 gravity can be controlled, just like the gravity of the earth.

The atmospheric composition is controllable, and the cost is low, and the effect is quick, unlike the effect of transforming planets that can only be seen for hundreds of years.

The temperature is controllable, unlike other planets that are either too hot or too cold.

Conveniently, the spacecraft can move, for example, to the asteroid belt for mining.
