because long ago a bunch of people got together and created a set of rules to determine length. one of those length measurements was called a "mile." then they measured how far away the sun is by determining the size of earth and how long it takes for the earth to travel around the sun.

I thought they measured the speed of light and then calculated how long it takes for light to travel and then figured out the distance from there.
