Volume 1 Chapter 26

Chapter 25 – Demi-humans (1)

It is said that ancient humans first encountered aliens about 15 billion years ago, after leaving the Physical Realm and becoming a Type V Civilization.

Actually, an encounter with an extraterrestrial being isn’t an easy feat.

Of course, it was difficult for a civilization to leave the star system where they were born, but the bigger problem was that it was rare for a lifeform to be born on a planet at a galactic level.

If you wanted to meet extraterrestrial beings (in the case where they did not approach you first), your civilization had to at least reach a level where they could leave its current galaxy without much problem. Of course, it would take a considerable amount of time to pile up a civilization from nothing, but the ancient human race cleared that condition and met up with a new lifeform, the extraterrestrial beings.

However, the first aliens humanity met were also humans.
