Think of credibility like a big, strong bridge that helps you trust someone or something. When you see a bridge made of strong metal and wood, you feel safe crossing it because you know it won’t fall. Similarly, when someone is credible, you feel safe trusting what they say or do because they have shown they are honest and reliable.
Imagine a superhero cape that only appears on people who always tell the truth and do what they promise. Just like you know you can count on superheroes to save the day, you can count on credible people to be truthful and dependable. This cape is invisible but you can feel it when someone is being honest.
Think of credibility like a jar full of marbles. Each time someone tells the truth or keeps a promise, they add a marble to the jar. If they lie or break a promise, they take marbles out. The more marbles in the jar, the more you can trust them. Having a full jar of marbles means they have a lot of credibility, and you can believe what they say.
