As someone who is older and had struggled with these questions, let me say this:

There IS a higher power !

How it works exactly is beyond human understanding !!

Glet, the answer to your question is ‘Karma’. That is why bad things happen and ‘God’ seemingly does not stop them !!!

Karma does not fit in with Christianity, Islam or Judaism but it is the central tenet of Hinduism and Buddhism. In fact, just like you, Lord ‘Buddha’ (who used to be a Prince) got confused by bad things happening to people – read his story.

You need to be a good person and do good deeds – that is all you can do.

Please don’t overthink this – over centuries, many intelligent people have gone insane looking for an answer.

GOD Bless !
