very loud sound ,round shape object in Louisville,Ky Southend

It had to be around or close to fourth of july because i remember us playing with glo sticks when this round shape object appeared it was very loud ,it glided over us almost hitting the apartment building thats how low it was we thought it was gonna crash,it was so big we only seen underneith it ,it had multible lights it was like layers of circles with lights around edges. As it glided around the building we ran behind tring to chase it but it was gone. The only place it could have went was navel ordance it is a millatary place thats beside the apartments,I dont no it vanished so fast. Anyone can give all six people a lie-detector test and all will pass with flying colors. There were so many people out there,when I tell people this story they think im crazy
