You see a shuttle, rockets flaming, land, and people get out to their new planet.
One man takes charge, and he makes all the decisions. But he does not have time to get to everyone, so many people are left waiting for hours to do a simple task. Finally, forced, he appoints assistant judges. But these, also have problems with too many decisions to be made, and unlike the first man, they are not incorruptible.
Technology slowly fails, and when people complain, they are sent to work camps, and then later to gallows. Eventually a generation later, a revolution succeeds. But by then technology has collapsed to steam engine level.
Later, steam engines cross the land, and then the Bollifers come. They demand goods. The small villages and cities refuse. So the Bollifers leave, but not before using one of their shuttles to send an asteroid to crash into the center of human civilization.
Once humans pick themselves up, its the Age of Mud with stick hoes, and a river than floods annually. Later, another Coming Star comes, but its not the Bollifers. And these newcomers take the planet up to the beginning of the Age of Stone...which you're in right now. Small castles, knights, villages, basic iron work....and a steady but slow expansion into the Wasteland.
