Short answer: We dont know yet.

Heres what we understand so far:

---

1. On Earth

As far as science knows, Earth is the only planet with confirmed life.
All plants, animals, and humans live here.

---

2. In Our Solar System

Scientists are searching for signs of life on places like:

Mars

Mars may have had water long ago. Rovers are looking for tiny fossil signs of ancient life.

Europa

Europa (a moon of Jupiter) may have a huge ocean under its ice. Water = possible life.

---

3. Beyond Our Solar System

There are billions of planets orbiting other stars.
Some are in the habitable zone, where water could exist.

But we have no confirmed alien life yet.

---

So are we alone?

Maybe yes.
Maybe no.
We are still searching.

Many scientists believe it would be surprising if life exists only on Earth but we need evidence.

If you want, I can explain:

• What aliens might look like
• Why finding tiny bacteria would be a huge discovery
• Or how scientists search for life

What do you think do you believe were alone?
