What role did the discovery of the Moon's rough surface play in the acceptance of Galileo's later findings?

Answer

It served as the gateway discovery that validated the telescope as a scientific instrument.

The Moon's imperfection was the first major piece of evidence against old models, confirming the telescope revealed tangible, physical truths, thereby paving the way for acceptance of subsequent findings like the Jovian satellites.
