What seemed to be crafts with bright lights rotating in circle formations descending to earth, then ascending later on.

I’m a first officer on a Boeing 737-800 cargo jet and while at 38,000ft just passed Albuquerque on a flight from Dallas to Las Vegas my captain and I noticed individual bright lights moving relatively slowly in a circular motion descending from the sky a few hundred miles north and well above our altitude. We couldn’t tell whether it was 10-20 circling lights or 4-5 circling around each other. After watching them descend from high altitude from west to east they later departed in the same fashion and ascended back into the sky in an east to west direction of flight. We looked up starlink’s position during our time of flight and it would not have been visible that night. These objects also traveled in opposite directions (originally descending West to East, then ascending East to West). These objects also did not appear to be other aircraft as there were no position or strobe lights visible, furthermore the bright lights were far brighter than an aircraft I’ve seen, especially at such high altitudes. The area around Grand Junction is our best guess. We were over Albuquerque at FL380 and the objects appeared North Northwest a few hundred miles and very high altitude.
Please do not release any personal information with my contact details until I give my verbal approval. Thank you so much.
