I dag er forskerne ikke l\u00e6ngere s\u00e5 sikre p\u00e5, at livet opstod p\u00e5 eller t\u00e6t ved Jordens overflade. Uanset hvor vi kigger hen, ser der ud til at v\u00e6re liv \u2013 selv flere kilometer under jorden. Det kan v\u00e6re, at livet opstod p\u00e5 havbunden, hvor varme kilder leverede energi i stedet for sollys.<\/p>\n<\/div>\n

En anden teori g\u00e5r ud p\u00e5, at livet \u2013 eller i det mindste de kemiske byggesten \u2013 stammer fra rummet. I Jordens tidlige historie ramte mange kometer Jorden. Kometer indeholder store m\u00e6ngder kulstofbaserede kemiske stoffer, som kunne have dannet grundlag for livets opst\u00e5en.<\/p>\n

Det er ogs\u00e5 muligt, at liv kan overf\u00f8res fra en planet til en anden. Det ser ud til, at liv er robust nok til at overleve en lang rejse gennem rummet. Hvis en stor komet eller meteorit rammer Jorden, kan den sende store m\u00e6ngder sten ud i rummet. Eventuelle bakterier, der befinder sig som \u00bbpassagerer\u00ab p\u00e5 disse sten, kan i sidste ende lande p\u00e5 en anden planet.<\/p>\n

P\u00e5 samme m\u00e5de kunne en meteorit fra Mars bringe liv fra Mars (hvis det fandtes) til Jorden. I 1996 meddelte forskere verden, at de havde fundet netop en s\u00e5dan sten fra Mars i Antarktis. Andre forskere s\u00e6tter dog sp\u00f8rgsm\u00e5lstegn ved deres forskning.<\/p>","protected":false},"excerpt":{"rendered":"

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.
