Care to explain how you come to this completely incorrect conclusion?

A digital signal is one that transmits information only using two discreet states (1,0 or on,off etc.)

This is exactly how the telegraph operated, the circuit is either open or closed, and information was encoded and transmitted as a digital signal.

The fact that the Morse code used on telegraphs has variable periodicity to its signal ( .,-) does not make it non-digital because the fundamental mechanics of the device allow only on and off.

The earliest digital information transmitting, however, would be flashing a light or using reflective materials to flash sunlight in a purposeful pattern.

Semaphore is an analogue signal medium.
