What did the ancients write with before bamboo was discovered?

At the earliest time, the ancients recorded things with sticks, then carved them on stones with sharp things, and some were carved on the Oracle Bone Inscriptions (that is, Oracle Bone Inscriptions). Everything that the ancients needed to record before divination was engraved on the Oracle bones. That's all I know. I don't know if it's right. Hey hey, forgive me!
