Hi, new here and fairly new to KSP as well. Just crashed on the moon though so I figure I'm up to speed enough to join the community, so hi! Funny theory I've got about planet kerbin, there's only 2 space centers and nothing else on the planet, yet there are a ton of kerbals. To me that means they're entire civilization is based on space travel which is pretty awesome if you ask me. This theory goes down the drain when they enhance Kerbin later but for now, their entire evolution and civilization progression has been devoted to becoming space travellers (note they have no unmanned missions ).
