GPS or Global Positioning System, have you ever used it? Google Maps or Waze, I use both quite often for directions when traveling in North America, and have used GPS in Europe and Asia. I've also used it for positioning while backpacking Denali National Park in Alaska, where there were only animal trails and streams to hike on. It is fairly precise and has always performed well, and is based on the earth being a globe. Oh yeah, many of those smart bombs and cruise missiles that we've seen on CNN etc., that are so accurate, use GPS.
How does GPS prove the earth is a globe?
How do you know they use satellites?
The ISS has supposedly been circling the earth 16 times a day for 20 years.
It has gone around the earth approximately 116,800 times.
There are supposedly over 4,000 satellites orbiting the earth.
And yet...
We have not a single photo of any satellite in space.
We also have exactly NO video of a rocket ever going from land to space.
What we have are a lot of fantastical tales.
You can being thinking any decade now.
