As we know, stars do not move. Stars are like our sun. They are stationary and do not move, but planets and moons do move. They orbit stars. Anyhow, why it looks like that stars move? As you watch the sky in early night, it looks different than later at night. Stars change their position as the night goes on. They start rising in early evening, reach the highest position after midnight and finally go below the horizon in early morning. Only the circumpolar stars do not go below horizon, but also their position in our night sky changes
lol... as always you just look some website up, do not even check it's source and try to see if it is correct and think it is..
This sums up why you also are a religious man, you are gullible and swallow any information you come across... so here's where you should have gone to read about stars.. stars are not fixed.. you should stop reading websites that talk nonsense and start reading official websites that actually have correct information..

"The stars may look fixed, but that is an illusion of time and space. They are so far away the human eye alone cannot detect their motions on the sky.
ASK THE ASTRONOMER
Have a question for columnist Jeff Kanipe? Now you can Ask the Astronomer.
Their apparent motion, measured over a year's time, is referred to by astronomers as annual proper motion. Because they are nearby, stars nearest the sun exhibit the greatest proper motion, while those at more remote distances appear virtually fixed. The amount of positional change is so small it is expressed in the angular value of arcseconds. One arcsecond is roughly equal to the size of a quarter seen from a distance of about 3 miles (4.8 kilometers).
Proper motion is a combination of the star's true direction and velocity in space, as well as its motion relative to our solar system. In our part of the Milky Way, stars move at an average velocity of about 15 miles (24 kilometers) per second. The sun, too, moves through space at about 12 miles (19 kilometers) per second toward the constellation Hercules.
Some stars, however, move at more impressive speeds. Arcturus, the brightest star in the western evening sky, shifts its position on the sky by 2.3 arcseconds each year. In 5,000 years, it will have moved 3 degrees on the sky -- an amount equivalent to six full moons -- in the direction of the constellation Virgo. At Arcturus' distance of 32 light-years this motion translates into a space velocity of about 90 miles per second, making Arcturus one of the fastest-moving first-magnitude stars in the sky.
The stars only look frozen. If we could reduce several million years of their motion to a minute's time, we would see many of the brighter ones racing across the sky like meteors. There really is no such thing as a fixed star."
