Why don't you start the career mode? It basically tells you what to do and is easy to follow.
Could be part of the problem, actually. Career mode gives you very limited parts early on, and that makes the simplest of things more difficult. You can also dig yourself into a hole and "lose" the game if you don't know what to do. I'd recommend playing around in sandbox mode to figure out how to do basic things, like building a rocket capable of orbiting Kerbin, then adapting/remaking it to be capable of transferring to Mun. Doing those things without any limitations put on you will teach a player enough about how the physics work to be able to problem-solve in career mode, without the looming threat of bankruptcy. I wouldn't dump a new player straight into career mode and expect them to progress very far.
