Witness an enormously long cylindrical craft

Was out walking my dog in my apartment complex at approximately 6:30 pm on December 3, 2021 when I noticed a unbelievable long cylindrical craft with a long single row of lights or windows decently bright enough to light the body of the craft enough up to see it was a long continuous grey cylinder of unbelievable length. This is what really blew my mind. My best guess in length would be 3 to 4 miles in total length. 30 to 40 semi bright lights or windows in a single row. Lights/ windows did not go to end of either end. Ends were lightless or windowless about 5 window/ lights in length on each end. Each end was rounded like a medication capsule/pill. Direction was coming from the west going east towards the ocean that is about 50 miles away. Besides guess at altitude would be 10 to 15 thousand feet. Sighting started near my unit which has a pool and pool house adjacent to my unit. Object first appeared in the area of pool. I watched for 15 to 20 seconds as it was moving east. There was light from from apartment windows and light poles making it hard to focus in object. After 15 or 20 seconds I ran with dog in tow to a field by the complex that has power lines running the length of the field. There were no lights to here to pollute my vision. Once in the field i watch the craft for another 20 seconds, but in great clarity this time. I got my best look at craft in this location. This is when I could clearly see it was a solid craft. I watch it till out of view over some tall pines. Once out of view I tried running to another area to see I could see it some more but the object was gone. No sound was heard during the entire duration of sighting.
