I've always seen strange lights and objects in the sky before, but I never really thought much of them. About a week ago though I saw some strange things 2 days in a row. The first day I was driving home and without thinking glanced into the sky and I saw a strange object, only visible one in the sky (besides the sun.) It was circle shaped and I suppose metallic? because I could see a glare the sun was making on it's right side. The object also was changing directions, going to the left, stopping for a little, then going back over to the right. It didn't have any blinking lights that I could see, just a shiny circle object.
Of course I almost crashed my car cause I was staring at it for so long, but when I got on a straight highway again I looked back up and didn't see it anywhere. But that's it for that day, the next I was driving from home to school (along the same road where I saw the circle object.) Not to far up in the sky, I saw many little dark objects seemingly appearing. For some reason at first it looked like little scraps of metal being thrown up, then I thought it might be a flock of birds or something, but the weird thing was that these objects weren't rising up or coming down from anything, they were literally just appearing in a straight a line. Keep in my mind this happened pretty fast, and when I drove underneath the objects and looked back they were gone.

Those are the 2 strangest things I've probably seen in my life, I can't explain them. Most likely they were something very explainable but if you guys have any ideas to what they were throw 'em at me.

P.S. Has anyone ever seen certain lights at night that aren't moving, but just seem to sit there blinking like crazy? I've see them every now and then but figured it just might be a satellite or something I don't know much about.

I see blinking lights all the time, nothing out of the ordinary I don't think.

About the flying things, go ahead and call them UFO's. Because that's really what they are, flying things that you've never seen before or can't explain. Whether or not they are of alien origin could be debated easily. I'd say just enjoy it
