If the speed of light is a constant 300000 Km/s then it would take longer than 6000 years for light to reach the earth from any star farther than 6000 light years away.
If you put a bunch of vegetables in a pot of water and stir vigorously, you get randomly distributed vegetables, not vegetables that are distributed with the simplest forms on the bottom and the more complex forms toward the top.
