I wish I could play the guitar.
If only I can see you in person, I can tell you more about how to play the guitar.  You play it by strumming or plucking the strings with your fingers while pressing against the frets on your other hand.
It sure sounds like it requires a lot of coordination.
It does take some practice - there are usually six strings that you need to press against the frets to make various chords and when you combine enough of these chords together, you get a song.
