re: But you said that UFO's do not exist.
Do you often see the moon and stars at 4 PM on a sunny afternoon?
Are you sure that you were not hallucinating the whole thing?
Were there others who saw it also?
Did anyone take pictures?
If you know who releases the balloons, why not ask if it belonged to them?
You said:
"it did NOT come down to abduct me and erase my memory,"
How would you know that, if your memory of the event is gone?
