Fleet of 20-40 ufos descended on house, stayed long enough for my family too see them, came way down and then left

Was in my back yard with my sister and Al of these hovering silent craft descended on my neighborhood right above my house anywhere from 300-500 yards up. We were staring at them when one came down to about 100 yards from the ground so we could see it perfectly and their were three large lights one red one green one blue that looked like square grids each in a line on the bottom of a silver oval shaped craft. Then they all flew off after about 5-6 minutes. My entire family had time to come out and see otherwise I’d be checking myself in somewhere.
