[SUPERMAN] Is there any real canon as to why Clark was sent to Earth?
gpt
Well the most basic answer is because Krypton was about to die, so he had to send Kal El somewhere.

As for why Earth? Well that is a bit tricky because there are many answers depending on which universe we are talking about, but what we do k ow is that Jor El at least knew about Earth and that the people there were similar enough physically for Kal El to fit in.
