Space is so vast that we can't imagine how many living beings are in the whole universe or maybe we can say Multiverse because there is no bounding.

As Kardashev scale is a method of measuring a civilization's level of technological advancement based on the amount of energy it can use.
Probably we can do that so how'll they look like compared to us?

For Example, let's do a comparison between level 1 and the level where we are, Type 1 Level Civilization can use all the energy present on their planet, From - Geothermal, Hydro Power, Tide energy, Wind energy, Solar energy, Nuclear energy, Biomass energy, etc. Present on earth, But we humans are not able to just install solar panels around the heavy daylight area than Geothermal is a long journey.

For that journey just STAY TUNED
