"Foo Fighter" chased by two military helicopters

Two military helicopters fly behind my house, Kipling and C-470, low and in arks, as if they are searching for an object or for a person. Leaving for the Costco at Wadsworth and Quincy, 7.3 miles north, I see the helicopters making the same arks as they edge north. Parking at the Costco, my wife does the shopping, I sit in the car. Faced north in the parking space, I see both helicopters. Between them is a bright light floating between some tree and 4-6 feet in diameter. The light coming from it is unreflected, and self-luminescent. Another person saw these helicopters at my home location another time along with two F-16s with afterburners. I've heard afterburners many times above the house. He reported it on NextDoor, but has since disappeared along with his report. I have seen 11 objects in my quadrant of the Denver-metro area. I just discovered this website.
