Why did the Perseverance rover find organic molecules on Mars?

The Perseverance rover found organic molecules on Mars because they were like clues left behind from ancient Martian life or something that acted like it.

Imagine you're cleaning your room, and under the bed, you find a few pieces of paper with scribbles. Those scribbles might be from someone who used to play in that room, maybe even your brother! The organic molecules are like those scribbles, they could mean there was once something alive on Mars, or at least something that did interesting chemical things.

Think of organic molecules as the ingredients in a snack bar. Just like how you need chocolate and nuts to make your favorite snack, scientists think certain organic molecules are needed for life, like how we use food to grow and stay healthy.

Perseverance found these ingredient-like clues in a place that used to have water, maybe even lakes! Water is like the oven in our snack bar analogy. It helps ingredients mix and change, just like it helped ancient Mars make organic molecules.

So Perseverance is like a little detective, and it found some really cool clues on its Martian snack hunt!
