You are suggesting that information was not existing before symbols?

Where and when information exists so do symbols, in the abstract sense. It’s not symbols as representation of meaning but symbols as mediating meaning.

That’s a strong claim that is not common. Humans are generally considered to be the only animals capable of symbolic thought [1]. Information flows in far simpler systems than symbolic systems.
