五、Scientists think that there has been life on earth for hundreds of millions of years. Seven other planets go around the sun like the earth. However, none of them has an environment like that of the earth. So scientists do not think they will find life on them. The sun and its planets are called the solar system. And our solar system is a small part of a much larger group of stars and planets. We call it Galaxy. Scientists have also discovered many other galaxies in the universe. So it is impossible to imagine how large the universe is. We have always asked the question: With so many stars in the universe, are we alone? Is there life out there in the space? We’re looking forward to know the answer.
