If humans are separated from N planets in the future, will they regard the earth as their home planet at that time, and will they contact each other at that time?

As the birthplace of human beings and human civilization, the earth is of great significance to human beings at any time, just like homesickness.

Some people say that if human beings don't enter the era of unification, they can't really start the era of the universe, but whether this is the case can only be verified by time. It is really difficult for human beings to want to be unified. Just like people from one country and another, if there is no special intersection between them, basically you will not regard him as a compatriot or even a relative, let alone a person from a different planet, but as a person who thinks he is the same as himself, he will still have a basic understanding. As for the connection, if humans can't break through how to realize the rapid connection between stars, or even reach them quickly, then the connection between planets is very difficult. After all, how difficult and far away it is to find a planet suitable for human habitation in the universe.

The United Nations formulated the Outer Space Treaty in 1967. In this Outer Space Treaty, all members of the United Nations signed and agreed that the sovereignty of outer space celestial bodies does not belong to any country.

However, if humans begin to colonize the universe, the situation may be more complicated. You should know how America came from. Native Americans are basically descendants of British colonists, but with the development of local culture, the American nation gradually formed, so there was the American War of Independence. If interstellar colonization is used, it is likely to happen on the colonized planet. In the face of how to use other planets in the future, you may still need to sit down and talk, or you can only fight.
