Information is an emergent property, it isn’t a “thing” in the same way protons and electrons are. We can for instance assign meaning to an arrangement of matter and it now “holds information” despite nothing at all actually occurring to the matter in question.

For example we might point at a flag and say “If the enemy is spotted and trouble is coming, lower the flag to half-mast to indicate distress. If the flag is up you are fine.” Nothing changed with the flag itself yet it now holds information.
