Oh...wow...
My hubby and I have seen these things several times in our lives...and they are either glowing orange or they look like gigantic silver ball bearings moving across the sky at unbelievable speeds.
I just do not believe that we, (humans), have that sort of technology...not in any country. So that leaves about only one explanation. And, when you have exhausted all other options, what you you have left, no matter how extreme it may seem...has to be the answer.
I also have to wonder just what else your mom saw that was so disturbing that she won't even talk to you about it?
