UFO Sighting in National City, California on 2016-07-09 20:46:00 - V for formation of 5 then 3 in a triangle form then 2 then 1 hovering alone

1.I was driving home with my family after grabbing some dinner to bring home . 2.My histband in the passenger seat kept telling me to look at something in the sky 3. i wanted to say the objects were planes or helicopters but they looked nothing like either of those . 4./6. when i first saw the objects there were fireball looking ufo's . there were 5 in a v formation flying steady in the same direction as our car. then as i drove off the freeway for a better look there were now 3 ufo 's in a triangle formation and the first ufo at the head of the triangle was speeding up in the same direction it had been (west) until i could not see it . then there were 2 that hovered over our city library until one of the ufo's also started to speed off west in the same direction as the other had . now there was one last and that had stayed hovered over the library for about 10 min . i got closer to see if i could hear sound or make out the object better . i couldn't hear sound or get a better look other than it looked like a fireball with green and red flashing light occasionally toward the end of my sighting . as my family was hungry i didn't watch to see what the ufo hovering did but as i left the scene it stayed hovered and had zero sound 5. my feelings were confused ,excited and interested .
