Line of 10-12 UFOs proceeding in linear fashion at High Altitude. Paso Robles, CA

I was taking a smoke break in our backyard in rural eastern Paso Robles, early in the AM very near to 5:15 - about 40 minutes ago.
 Let me say at this point that this is my first DEFINITE UFO sighting. I have been vaguely interested in UFOs for their entertainment value, but I've always been darn skeptical of their existence.
 I always like to look at the stars in the morning. This was impossible to miss. In the East-Southeast sky almost directly overhead, there was a long line of "stars" moving in a slow manner. The Line was almost perfectly linear. Their brightness was appx. that of nearly the brightest star at this time of morning.  They moved appx the same speed a satellite would, but they were clearly brighter than any satellite would appear this late in the morning.  And somehow we could tell that they were nearer to earth than a moving satellite, although their altitude seemed very high.
 There was absolutely NO sound associated with them, and it was very quiet with zero traffic noise, etc.  They moved from northwest to southeast, at constant speed.  Once they got fairly near the horizon they disappeared one by one.  I believe there is no moon or very little moon today, and there was no glow from the sun in the east (too early).
 I gotta say, this is my first Definite UFO sighting that can't be written off as something else.  Unless the military has craft that can fly at such extreme altitude without noticeable sound, or there are "squadrons" of low earth satellites being produced.  JUST INSANE !  I tried to film the line of moving objects with my wife's phone but I don't think it turned out.
