Gold orbs racing down my street about 10 ft off ground.

Out of my living room window I saw a group of about 20 bright gold balls about the size of a kids playground ball, bit bigger than a bowling ball, go down the street about 10 feet off the ground.   They were traveling at about 60 mph.  They were very bright gold, but I don’t think they emitted light.  I stood & walked toward window & another group of about 30 came whizzing by.  Then a third smaller group with one falling off from the pack toward the ground.  My cat had been sitting in the window but ran away when the balls came.  My husband refused to take me seriously or stand up to look.  They were completely silent. There was nothing on the ground near my house.  By the time I got outside they were gone but I was scared.  A moped had just gone by in the opposite direction.  By time he was out of earshot the balls came.  There had been light rain on & off that day but clear at the time. Rained harder an hour later.  Was this ball lightening???  I’d like to be contacted if! you can.  Thank you   Too fast to get a photo, phone not handy.
