if you have ever helped out in the community or played any sport or been in any type of club (chess, art, book club) when I say club I mean one that is well know not like Pokémon club don't put that on there also put what you are good at what is the highest education that you have had so far. what your goals are for yourself in the professional world etc..
the point is that you don't have to have job experience to make a resume( I made my first one in 7th grade for a project and I just add on to it when something come around)
so make a resume it might seem confusing but ask an adult to help you are someone that you trust to help you fill in the blanks.
Oh yeah if you ever got any awards for anything (a-b honor role, 1 st place in the science fair, rating of a 1 in solo and ensemble) put that in there it will show your future employer what type of person you are
I believe in you and if you have any questions please let me know and I hope this has helped
