In the past, people believed that the Earth was flat until someone proved that it was wrong. Now people believe that this earth is flat, despite all the evidence that it is completely wrong... Over the past 50 years, there have been numerous photographs of Earth from satellites, proving that the earth is shaped like a BRIDGE. Yet people still do not believe, even some people try to fly in the air with homemade rockets to prove the opposite. This is a daunting trend, the Internet users lack knowledge may be. Easily fooled, kids will probably have a misconception about the planet they are living in. If the Earth is a plane, the two stakes will have the same or nearly identical shadows, as they will all have a vertical angle. with the ground. Because the two balls of the two different piles, inferred two piles towards the sun in two different angles, we can conclude that the Earth is spherical. Or you can pick up the phone, call the person on the other side of the Earth to see if they are day or night. Unlike you, this Earth can't be flat. There are many ways to prove that the Earth can't be flat, but sadly until now we still have to prove that the Earth is spherical.
Satellites are a hoax, nothing but weather balloons and radio signals from the ground. The images NASA claims are from space are taken from a high altitude with a wide angle fisheye lens, a composite of high altitude images or just CGI and photorealistic paintings.
The Earth is flat and the light casting the shadows is divergent i.e. it spreads out as it travels like all light from a point source does and, the source of the light, the Sun in this case (the distance to the Sun can be measured with a sextant and it's about 3,000 miles) is close then, the shadows from two sticks will cast the same shadows as if the Sun's rays were all parallel and the Earth's surface were curved.
The Sun is close (3,000 miles) and small (32 miles wide), anybody with a sextant can measure and prove this.
The light from a close small Sun can't travel all the way across the Earth, perspective, convergence and various atmospheric effects limit the distance the light travels. This results in day & night as the Sun circles above.
The only sad thing here is the gullible fool who can't speak English and thinks the Earth is a spinning globe.
