[DC] Did kryptonions know they became godlike beings under a yellow sun? If so, why stay on krypton?

So, the kryptionions could, under the light of a yellow sun, instantly jump from "normal dude" to "among the most powerful beings in the universe".

Did they know this? They seem more then advanced enough to travel faster then light (in the DC verse, it's not even that hard) and there are lots of yellow suns out there. It only takes one kryptonian to explore some other world and boom, instant physical god.

So why not all move to a planet with a yellow sun? Why stay on the planet where you're a boring person when you can take a short spaceship ride and become tough enough to fight literal gods? Were they all just really lazy? Did they just coincidentally never find another planet with a yellow sun? If we found a planet where living there made us all-powerful we'd go there in a heartbeat. Why didn't they?

Yes, they did. They actually started conquering the universe.

> So why not all move to a planet with a yellow sun?

Some did, but because their religion heavily revered their solar system's sun as a god (it actually was), their leaders and such remained on Krypton.

Edited your question to better suit the information. So, eventually the religions leaders claimed that their powers were the work of demons and that everyone has to return to the purifying light of Rao (their sun god). Kryptonians that disobeyed were taken down by those who were obedient to the church. Others went into hiding, but it turns out it's super easy for them to develop weaknesses as an offshoot of Kryptonians called Daxomites became weak to lead.
