Create an event?

So someone stole my bicycle from the garage last night. I can see this by watching footage from that time because a ring "event" never registered. The 36" door to garage is directly across from the ring camera and our front door. At 1:30 the outdoor lights came on (motion detector). Then suddenly that 36" door is open. A few seconds later the light inside the garage is on. The main garage door never goes up. About 10 minutes later all the lights cease. At no time did I see a person or a bike. It is so strange. So I would like to save that section of video to show others but because there was no event registered, I don't know how to do that. Any ideas?
