On 7th August 1996,NASA (1) scientists made an announcement that made front page headlines throughout the world.Within a Martian meteorite,they had found evidence of a microscopic lifeform that may have existed on Mars more than three billion years ago. (2) Although other studies were later published which challenged this conclusion, (3) numerous recent discoveries,for example,the discovery by the Galileo spacecraft, (4) in February 1997,of a possible red-coloured sea under the ice crust of Jupiter's moon,Europa, (5) are raising hopes that we may soon be able to get an answer to one of the oldest and most interesting questions asked by humans-"Is anyone out there,or are we alone in the universe?" However,it may be that none of us may live to see the day when scientists will give us a definitive answer to this question.For Muslims,that should not be a problem.We already have the answer.Although many Muslims are unaware of the fact,the Quran (6) explicitly mentions the existence of extraterrestrial life.
