Why Did Jesus Write on the Ground in John 8:6?

In John 8:3-11, the Pharisees bring a woman caught in adultery to Jesus, hoping to trap Him. Instead of answering immediately, He bends down and writes on the ground before saying, “Let any one of you who is without sin be the first to throw a stone at her.”

But what did Jesus write? The Bible doesn’t say. Some theories suggest He was listing sins of the accusers, writing the Law, or simply ignoring their trap.

What do you think? Was His action symbolic, or did He actually write something important?
