Smoking gun

Okay kiddo, imagine you are playing a game of detectives with your friends. You want to find out who ate all the cookies from the cookie jar!

A smoking gun is like a clue, or evidence, that can help you figure out who ate the cookies. It's called a smoking gun because it's usually something that is really obvious and can't be denied.

For example, let's say you found a piece of cookie stuck in your friend's teeth. This would be the smoking gun in your investigation because it's clear evidence that your friend ate the cookies!

In real life, a smoking gun can be something like a recording of someone admitting to doing something wrong or a piece of evidence that shows that a person was at a certain place at a certain time. This evidence is really important because it can sometimes be the key to solving a crime or figuring out who is responsible for something.

So, just like in our game of detectives, a smoking gun in real life is a really important piece of evidence that helps us solve mysteries and figure out what happened.
