Sphere looking object with extremely bright lights and one blue light, none of them blinking, hovering over Ga. 400, exits 12-13.My daughters and I were heading home from church, northbound on 400 around 9:00pm, between exits 12 and 13, just past the Siemens. I spotted a bright object in the sky up ahead and as we were talking, I kept noticing the object wasn't moving and was getting closer, meaning we were moving and the object wasn't.I finally said to my daughters, "Look at that thing in the sky." Neither of them believed and didn't look up...I am always pulling jokes on them and being silly. One of my daughters said it was probably a star, sarcastically, but the night sky was completely overcast...not a star in the sky. The back drop was an orange tint to the skyline.When I finally said it again, we were almost under it and my curiosity grew when I didn't see a pole anywhere in site. I was thinking it was one of those towers with brinking lights, only they weren't blinking. As we got right under the object, my other daughter finally looked out the window and almost cussed, saying, "Holy.....oh my gosh dad!!!!" She rolled the window down and started making out what she was seeing. She said it was a longer shaped sphere, no wings, no propellers, about 300-400 feet in the air. There were 2 extremely bright lights on either side of the object and a blue lights that looked like it was underneath or coming from inside. It hovered, completely motionless as we passed by....my other daughter wanted to see it but the other daughters head and body were in the way. I told her to look out the back window and that's when they both said it was gone....I pulled off of exit 13 and drove back down to exit 12 to see if we could see it again and unfortunately, it was gone.I am posting this because I don't believe in aliens, but I can tell you that I have no idea what we just saw, and want some answers. Just the fact that I am posting this on this site is enough for me to ask, what the heck was that?
