The short answer is no. There cannot be one planet and one person with a single government. However, it might be possible to have a group of people with a shared government that governs more than one planet.

The long answer is a bit more complicated. There are many factors to consider when asking if it is possible to have one planet and one person with a single government. 

• The first factor is whether or not the people of the planet would be willing to be governed by a single government.
• The second factor is whether or not the planet would be able to support a single government. 
• The third factor is whether or not the people of the planet would be able to get along with each other under a single government.
• The fourth and final factor is whether or not there is a way to create a single government that would be able to govern more than one planet. This is the most difficult factor to consider, as there is no easy answer. It is possible that a group of people could create a government that could govern more than one planet, but it is also possible that such a government would be unable to function properly.

Is it possible to have one planet and one person?

The idea of a unified Earth government is not a new one. In fact, it's something that has been proposed many times throughout history. The most recent attempt was the formation of the United Nations in 1945.

However, the UN has failed to achieve its goal of uniting the world's nations under one banner. There are many reasons for this, but the most important one is the fact that the UN is a political body and not a governing one.

So, is it possible to have a unified Earth government?

The answer is yes, but it would be very difficult to achieve. The main reason for this is that there are so many different cultures and traditions around the world. A unified Earth government would have to take into account all of these different factors and find a way to accommodate them all.

Another reason why it would be difficult to achieve a unified Earth government is the fact that there are already many different governments around the world. These governments would all have to be dissolved in order for a new one to be created.

However, even if all of these obstacles could be overcome, there is one other major obstacle that would need to be addressed: the issue of power.

Who would be in charge of this new government? Who would have the final say in what happens on Earth?

There is no easy answer to this question. However, it is worth noting that the concept of a unified Earth government has been gaining traction in recent years. In 2015, the UN General Assembly adopted a resolution calling for the creation of a 'United Nations Parliamentary Assembly' (UNPA).

This UNPA would be a body of elected representatives from all of the world's nations. It would have the power to pass laws and make decisions on behalf of the people of Earth.

The UNPA would be a step in the right direction, but it is only a first step. For a truly unified Earth government to be created, much more would need to be done.

In conclusion, it is possible to have a unified Earth government, but it would be very difficult to achieve. There are many obstacles that would need to be overcome, and the issue of power would need to be addressed.
