After some more talking, Theodor finally believed Kyle.
Naturally, believing that there was another world was especially hard for someone who had grown up in this world.
On Earth, people knew about the universe and other potentially hospitable planets.
Another hospitable planet was kind of like another world.
On top of that, plenty of fiction focused on other worlds with different rules.
Meanwhile, this world was surrounded by walls and a ceiling, which essentially had the sun painted on it.
Yet, Kyle's proof was about as solid as it got.
Coming up with one interesting concept was one thing, but Kyle essentially came up with many different concepts and created prototypes of these machines in a short period.
One person couldn't be that creative.
Surprisingly, Theodor didn't ask a lot about Earth.
Kyle had expected that Theodor would ask more about Earth, but he didn't seem interested.
