It's because our angle of vision.
Imagine a car passing next to you at 100 mph, it only takes a couple of seconds for the car to get out of your sight (assuming you don't move your head).
Now imagine an airplane moving at 500 mph, thousands of feet's above the ground. Although it's moving way faster than the car, it takes longer for the plane to get out of your sight.
The same applies to what we see in the night sky. Things are moving, really really fast, but they are so far away that we still can see them.
stars and constellations are at different distances from earth
stars of the same constellation are at different distances from earth
if a star in a constellation is 800 million miles from earth and another star in that same constellation is 900 million miles then that further star has to be moving precisley slower or faster in order to keep integrity of the constellation
if science can only claim a very small fractional amount of movement or differentiation in the constellation over a large amount of time 350 years you can bank on they have no clue wats really out there
your comment was so irrelevant and stupid entirely missing the argument
