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.

Answer 1

Because the Germans Plastered the UK with dumb bombs , many of which didn’t go off.

And we did the same to them.

We are talking thousands of Bombs on almost a daily basis for over a year.

I’m not 100% sure if this is the absolute truth , but in the early days of WW2 bombing was kept to strategic targets only. German Bombers Bombed civillians in the UK by accident.

Which then led to the British responding by Bombing German Civillians.

Then the gloves were off and Bombing civillians became the norm for the duration of the blitz.
