How are WW1 or WW2 era bombs still regularly found in gardens and houses around UK and Europe?

Question

The day after or week after these were dropped 60-100 years ago, did people not think, there’s a bomb over there we should make it safe.

Edit: I singled out the UK because they discovered a bomb from World War Two today in Plymouth. I know the UK is still in Europe.

It wasn’t a case of a few bombs being dropped. In an artillery barrage of WWI or an air raid of WWII, there would be thousands of bombs or shells dropping in a single night. People were naturally taking shelter for safety so they weren’t looking at each and every bomb falling. bombings were often at night, and cities deliberately blacked out lights so that aircraft could not tell where they were. If 1000 bombs drop in one night over a city, it is really easy to miss a couple. If this happens for a couple of years, night after night, that’s a lot of bombs you just didn’t notice,
