Floating light formation kept hovering and dimming in and out but zero movement what so ever

My mother came to visit my house I lived in last year in San Diego. We were watching tv that evening and I have a very clear view of the beach outside my window and something caught my eye. I am used to seeing naval ships, airplanes, drones, helicopters, and more off the coast but this was something unusually spectacular. A formation of five separate lights appeared hovering during sunset. I thought to myself oh it’s probably drones or some military exercise but then as the sun was setting, I could see the boats in the ocean turn on their lights and then saw an airplane flyby and realized this is something crazy. I jumped up and told my mom “OMG mom there is a ufo in the sky and now my life is complete!”. I have always been a huge believer in existence outside of our planet and my mom was not a believer until this incident so we started recording. The biggest thing that stood out was the comparison of distance vs height and illumination of the lights vs the planes that were passing by and the ships underneath the floating objects. There was no sound or movement from these objects other than appearing in and out in a formation. We could even hear the planes next to it but zero noise from these objects. This was something our minds could not comprehend. The lights were so big and bright and closer then the planes but we couldn’t see anything but hovering lights. Then the formation started to fade it’s lights in and out. Then reappeared but always in the same hovering formation. There was zero movement until the lights would dim then reappear in another pattern. This went on for about 30 minutes just hovering in a stacked a weird very bright light formation. I have gifted drones to people and this was not a drone. This was not a flare gun exercise seeing these lights were not falling at any point. This was not a plane, seeing it was stationary. This was something EXTRAordinarily terrestrial. No one believes us when we tell them. It was something you had to be there to experience but many people all along the coast reported the sightings. The next day, articles came out about it stating police were informed and claimed it was not known what these lights were. The military did not take ownership the next day, no one knew besides us residents that saw the spectacular event.
