Bright light or lights that brightened, hovered, flashed, moved downward and disappeared, but were replaced by a new light.

My son called me to our window which overlooks the larger city near where we live. He told me that he saw a UFO. I was skeptical and went over to acknowledge, but reassure him and what I saw out our window was brighter and more pronounced than what my video captured. This is my first time to report any sighting. We usually see lights from the city outside our window, but this was different, enough for me to stop and figure out how to report this. The bright light flashed at times and seemed to move at other times. I noticed other strong lights that appeared, came nearby and eventually replaced the prominent light after it lowered and was no longer visible. Some of the lights appeared and disappeared, then reappeared. They all moved toward the same general space when they disappeared. I don’t remember exactly how many I saw altogether. My mother saw the light briefly just after I did with my son.
I work as a mental health therapist. I have two master’s degrees which pertain to my work. I have always been a skeptic about UFO encounters until the past few years, when I have learned more, and am still selective on what I pay attention to online and in the media. I am reporting this because this was unusual and something I haven’t seen before here. I have additional video, but it was too long. I can submit it later if it would help.
