Because it feels that way to all of us.
Many people believed that Earth was the center of the universe because it appeared to be stationary and everything in the sky seemed to revolve around it. This geocentric model was also supported by religious and philosophical beliefs of the time. It was not until later scientific discoveries, such as those made by Copernicus and Galileo, that the heliocentric model of the universe began to be accepted.
People used to think that the earth was the center of the universe.
Aristotle thought the earth was at the center and the sun surrounded the earth.including the planets and moons.
As proposed by the Heliocentric Theory, the Sun is the center of the Solar System.
It has the Sun is in the middle of the solar system with all the planets revolving around the Sun. It is also called the "heliocentric model" of the solar system. It is the model we use today and is now known to be the correct model.
The Universe is 'space' however space is described as outside of Earth's Orbit whilst the Universe is everything. Earth is in the Universe but not normally in 'space' This is of course talking about normal usage. Scientifically/ Astro-physics level I think there are very minor differences.

the earth
Aristotle believed that the Earth was at the center of the universe, with all other celestial bodies revolving around it in a series of concentric spheres. This geocentric view of the universe contrasted with the later heliocentric model proposed by Copernicus.
it is earth
Yes, for close to 1,400 years everyone believed the Earth was the center of the universe. It was not till 1543 that a man named Copernicus created a model with the sun as the center of the universe. The Catholic Church clung to the idea of the Earth as the center of the universe for over 90 years.
In the 17th century, different people at different places started to accept the idea that the Earth was not the center of the universe. Copernicus had put forward a description with the Sun at the center of everything.Depending on what perspective you want to take, the center of the universe by some religious teachings is Mecca. One could say that the progression of beliefs was, Mecca, Earth, Sun, Milky Way.Now, we know that with an expanding universe and general relativity, one can say there is no place that is the center of the universe or every place is the center of the universe.
because they're dumb because they see and think that all thing around them move while they were fixed.
You're thinking of Galileo; however, the fact that he had to deny, or "abjure," was that the Earth orbited the Sun instead of the other way around. People probably did think of the Earth as the center of the universe, however, the concept of "universe" was nothing like what it is today. Even the term used, "cosmos," meant both "universe" and "world."
that the earth was in the middle of the universe
Aristotle thought the earth was at the center and the sun surrounded the earth.including the planets and moons.
... because they thought they were the most important in the universe and the only things in the universe so they thought they were in they centre.
As proposed by the Heliocentric Theory, the Sun is the center of the Solar System.
