As we hear this lately from TV and internet, there are so many news about UFO.
But, are they really exists?
That’s the question we usually ask. But i don’t ask that here.
My question are (although i will show my idiot) :

1. Why the scientists always looking for water at the other planet?
2. Is the existence only exists if water exists?
3. What if the alien doesn’t need water?
4. What if their basic need is dust? is sand? or just light or cold temperature?
5. What if they have something as their water? Not like water we know here.

Will scientists answer my quesion if they read this? I really hope that.
