Another verse of the Quran, however, makes it clear that there are many earths (see Quran 65:12). Is it possible that there may be other earths out there? 
No one expects to find another earth within our solar system. But scientists say it is likely that in our galaxy there are many earths outside the solar system. They say that approximately 50 billion stars in the Milky Way rotate slowly, as does the sun. This characteristic indicates that those stars are surrounded by planets that are their satellites. The Bernard Star, for example, is believed to have at least one planetary companion. (see The Bible, the Quran and Science, p. 148). Dr. Bucaille quotes P. Guerin as follows: "All the evidence points to the fact that planetary systems are scattered in profusion all over the universe. The solar system and the earth are not unique" (p. 148-9). 

In a recent article published in the Toronto Star, two scientists advanced evidence that there may indeed be many earths waiting to be discovered. The headline read: "Earths may be dime a dozen out there." 

The Quran also uses the symbolic plural number 7 to indicate the existence of a plurality of heavens (see Quran 2:29, for example). Dr. Bucaille comments that this is "confirmed by modern science due to the observations experts in astrophysics have made on galactic systems and their very large number" (p. 150). 
Once again we find that the Quran says something and scientists later discover it to be true. Can we resist believing in this book of God? God says: "Those who disbelieve in the Reminder when it comes unto them (are guilty), for indeed it is an unassailable Scripture. Falsehood cannot come at it from before it or behind it. (It is) a revelation from the Wise, the Owner of Praise" (Quran 41 :41-42).
