Or:

• Satellites (you can set your watch by their appearance time, even ones too dim to see with the naked eye. It ain't all about the ISS...)
• Navigation where you can't see Polaris (this still cracks me up)
• Navigation over the surface of the Earth
• The horizon
• Measurable curvature of the Earth
• Pressure differentials related to hight
• Time dilation due to speed (this is experimentally verifiable, btw)
• Time dilation due to gravity (this is how GPS accuracy is maintained, btw)
• The South Celestial Pole (YOU CAN LOOK UP AND SEE IT! The southen constellations rotate around it)
• Seasons
• Eclipses (solar and lunar)
• Surveying
• Aircraft flight times
• And that's just off the top of my head.
  

There are quite a few things Mr Fallacy needs to explain for his model to actually gain any traction.
