[DC] Wait, so you're telling me the entire planet Krypton only has one space-travelling ship?

and it's made to fit only a baby? Why isn't there any other space ships lying around Krypton? Kal-El's parents could've went with him. Why didn't Jor-El design a ship just a little bigger to fit his entire family at least?

Kryptonese society had gone into a post-exploratory phase, and they were in active denial about the potential existential environmental threats they were facing. While not outright xenophobic like their cousins the Daxamites, the Kryptonians simply did not have any pressing interest in space travel, and even Jor-El did not make any preparations until far too late, with the limited resources available to him.
