五、Scientiststhink 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 hasan environment like that of the earth. So scientists do not think they willfind life on them. The sun and itsplanets are called the solar system. And our solar system is a small part of amuch larger group of stars and planets. We call it Galaxy. Scientists have alsodiscovered many other galaxies in the universe. So it is impossible to imaginehow large the universe is. We havealways asked the question: With so many stars in the universe, are we alone? Isthere life out there in the space? We’re looking forward to know the answer.
