If you take the speed of light rounded up to 300,000,000 meters pr second and divide 40,000,000 meters into it which is the distance around the world, we get the time it takes to go around the world once at the speed of light. The time it takes is .133 seconds. I round that down to .1 for easier math today. What this means is we can do something at human speed that takes a human one second–like draw a small circle and when we draw that one small circle that took us one-second to draw, someone else who knew how to travel at the speed of light would be able to go around the world 10 times. The person traveling at the speed of light would be able to come check on us drawing the one-second circle 10 times in one second to see our 10th of a progress on the circle each time around. That is how SLOW we move compared to the speed of light.
For a human to go around the world it would take an airplane that travels 253 m/s roughly 44 hours. Now compare our reality of .13 seconds for light to get around the world to 44 hours it would take an airplane traveling at an average speed of 567mph aka 253m/s. They both mean exactly the same thing depending on which eye is used to travel around the world because time does not change as it is determined by the constant speed of light.
