One simple and definitive proof that you are not living on a spinning ball orbiting around the Sun is the fact that daytime and nighttime never switch places as they must for the heliocentric model to be true.
According to the globe doctrine, Earth makes one complete rotation on its axis every 24 hours, while simultaneously orbiting around the Sun and completing one full revolution every 365 days.
If this was truly happening however, as you can see from the following image, the daytime and nighttime sides of the globe would have to flip every 6 months.
