It's pretty dependent on what exactly you want to do, but I have found the Signals Music Studio channel to be a great resource for learning some music theory and composition stuff. Music theory is not a necessary entry point per se, but it can help to get some basic concepts into your head to play around with. But really, the best thing you can possibly do is just pick something that seems adjacent to music you like and just start screwing around (if you're a metalhead, maybe guitar, if you like EDM, pick any DAW, if you like jazz, get a decent midi keyboard, etc). Music really isn't an intellectual exercise, just start doing something, see what you like, and what you don't like. I wrote this comment a while back on learning music theory, which has some more thoughts and also some links and pointers to various tools and resources: https://news.ycombinator.com/item?id=37078383 https://news.ycombinator.com/item?id=37078383.
