Well, when I was a kid . . . . the VCR was not invented yet. So my editing consisted of cutting the 8mm film, brushing some liquid acetone-based glue at its end, and pasting it to the other section of the film.
Yep, my fingers were always messy with that acetone thing. It smelled nice, though. Years later I found out some kids actually got addicted to sniffing it, so I am sure glad that did not happen to me!
