UFO Sighting in Louisville, Kentucky on 2017-06-02 18:20:00 - White orb flying very high altitude with fast speed abrupt change in direction

I was outside on my back porch with my 2 children. i looked up and saw a plane and to the left of the plane coming from the east was a white orb traveling at a very fast rate. it must have been extremely high in altitude. there were no trails which immediately caught my attention. at first i thought it was a bird, but it was flying very quickly in a very straight line. after following it for about 10 seconds it immediately took a 90 degree turn north and after about 2 to 4 seconds it zig zagged very quickly before i lost my view of it. the object was way too high to be a drone and looked like an orb or white sphere. when i pointed to it my 6 year old daughter she claimed she saw it too. my 9 year old son did not see it though. i wanted to video it with my phone, but i knew if i took my eye off of it i would lose it because of the altitude. also i think if i were to video it then it probably would have been hard to see on the video.
