I saw object out of the corner of my eye while in a car. once stopped in the area i watched the object move very slowly over the area. descending at times and seemingly circling but not sure. then several more became visible some larger in size, at that time an airplane passed at about the same altitude giving me a comparison in size at that altitude. most were about the size of small cars. all kept moving appearing to circle while one seemed to hover and change altitudes. i wasn't sure what to think but i knew they weren't planes or drones. i had a witness to it with me and we both weren't sure what we had witnessed.
