Well, technically, a pencil has the lead and it uses something to compress it to write the information needed. BTW's, in history, Egypt used a stylus to write. But, as my inference, I say it came from there to us. In some way shape and form they let us use their technique and we, the people, took it from there.

Yes, graphite is the right answer because it allows all the carbon particles to arrange themselves in such a way that they form a parallel line to each other and allow the graphite to work smoothly like a lubricate. And also before they were using lead which was very poisonous and dangerous then they started using this graphite instead of the lead in the pencil "which is smooth, dark or black in colour.
