Q. Do you think there is life on other planets? Can you guess what kind of people there may be on them? In what ways are they likely to be different from us?

Ans. Scientists are trying hard to find out if there is any form of life on planets around the sun. So far they have sent spacecrafts to the moon and Mars, collected samples of soil and taken snapshots. But they have not found definite proof of life on them. The kind of people, if they exist at all on any other planet, would be quite different from us. They must have adjusted themselves to strange and unfriendly environment there.
