They didn't. Catapults and balista's were first used in the roman empire.
The Romans first invented them,
if they were invented, every buddy, or China.
The ballistas were crossbow-like catapults. They helped the Roman army. They were the artillery of antiquty.
The Roman Empire introduced the arch, and was very good at roads, stadia, catapults, etc.
Yes, they were around in Greek and Roman times.
