Today, scientists are not so sure that life began on or near the Earth’s surface. Everywhere we look, there seems to be life \u2013 even several kilometres underground. It may be that life began at the bottom of the oceans, where hot springs provided energy instead of sunlight.<\/p>\n<\/div>\n

Une autre id\u00e9e veut que la vie \u2013 ou du moins les briques \u00e9l\u00e9mentaires chimiques \u2013 soit venue de l'espace. De nombreuses com\u00e8tes sont venues s'\u00e9craser sur la Terre au d\u00e9but de son existence. Les com\u00e8tes sont riches en produits chimiques carbon\u00e9s qui ont pu donner naissance \u00e0 la vie.<\/p>\n

Il est \u00e9galement possible que la vie soit pass\u00e9e d'une plan\u00e8te \u00e0 une autre. Il semble que la vie soit suffisamment r\u00e9sistante pour survivre \u00e0 un long voyage dans l'espace. Une grande com\u00e8te ou m\u00e9t\u00e9orite s'\u00e9crasant sur la Terre aurait pu projeter de nombreux rochers dans l'espace. Les bact\u00e9ries qui habitaient ces rochers ont m\u00eame pu atterrir sur une autre plan\u00e8te.<\/p>\n

De la m\u00eame fa\u00e7on, une m\u00e9t\u00e9orite provenant de Mars a pu apporter une forme de vie martienne (si elle existe) sur la Terre. En 1996, des scientifiques ont annonc\u00e9 au monde avoir trouv\u00e9 un rocher martien dans l'Antarctique. Mais d'autres scientifiques ont quelques doutes sur cette affirmation.<\/p>","protected":false},"excerpt":{"rendered":"
