I thought of that idea too, that aliens are making their space ships look like stars, I dont want it to be true though, because thats so damn confusing for us. We dont know if its a extraterrestrial or a Godly matter... Personally, I believe its a Godly matter (but Im sure aliens have something to do with it too, also sure that some try to look like stars)... That big bright star you are talking about is the North Star, everything revolves around it and its lined up with the earth so it appears that it never moves... If you look above the North Star theres other stars that appear to be forming a Fibonacci Spiral (Found throughout nature, google it) also if you look around the sky you will see that theres a lot of straight and curved lines if you connect the dots. My theory is that the stars are starting to form geometric patterns in order to prepare for something new. (Heres why geometric patterns are important, note it says that aliens also fancy these geometric patterns

I've also seen one of the brighter stars move towards two other stars and form a perfect triangle before taking off at light speed beyond the other two stars... Anyways, back to the aliens. I only seen one flying light in the sky that was for sure an alien space craft and that was on 420. It was a line of evenly spaces lights that flew like a flock of geese in an arrow formation, but then it started squirming around rapidly, it looked exactly like a worm spazzing out, flying through space (or perhaps closer to earth) it was nuts!
