In 1963, Rasiya physicist Nikolai Kardashev divided the Universe civilization into 7 types on the basis of energy consumption. Let's try to answer you on the same basis.

Type Zero Civilization - Based on the energy we consume, our existence in the universe is zero at the moment.

Type 1 Civilization- Suppose there is an Earth-like planet in remote space, if people are developed from us, then the technology there will be 200/500 years ahead of us. Those people use 100% of the entire energy coming to their planet, which includes solar energy, wind energy, and water energy. They are capable of controlling earthquakes, weather, and volcanoes.

Type 2 Civilization - People of this civilization use 100% of the energy of their own star. For these, it seems to come to the surrounding planets. People of this civilization make Dyson spheres (giant circles) around their star and control the entire energy emanating from it. This technology is 1000 to 2000 years ahead of us. This type of civilization is estimated to be around Star KIC 8462852!

Type 3 civilization - the species here will be a mixture of bio-Robo. Its technology is 1 lakh years ahead of us. People of this civilization control and use the energy of their galaxy's stars. Here Dyson robots build the sphere to surround the stars. The vehicles here are huge and run at great speed. People here know where to make full use of energy.

Type 4 Civilization - Residents here go to their neighborhood galaxy to harness the energy of stars. People here are capable of manipulating atoms, creating nanotechnologies at the atomic scale and complex forms of artificial life;

Type 5 Civilization - People here are believed to have lived in a black hole. They are capable of creating and destroying the universe. The source of their energy is unknown.

Type 6 Civilization - Here people reside supreme and beyond our thinking. Which are able to control space, time at their own will. They have a monopoly in building and destroying anyone.

Type 7 Civilization - It is far ahead of our imagination. Maybe the abode of the best, almighty God here.
