Late evening over east lake star watching access to lake looks west to the south was watching what appeared to be a weather event told those I was with it looked strange. Took them back and returned to lake. Large craft over lake Michigan marked by cloud cover could tell by lights and very slow movements. Thought that a ship this size would have scouts, saw first to the west at 1 o'clock and 2nd south west 10 o clock. These were smaller be not single pilot cart both pulsing lights around ships seemed stationary but moved in altitude lights did not circle but ran from side to side to central point. Large craft to the south was stationary there was civilian aircraft between larger craft rotates 90degrees showing the bottom of craft which looked like stars but in a 4 point pattern. At this time I thought it was 2 crafts continued to watch scouts once a civilian craft was by all ships moved west slowly
