Sohterlifewil cntinue o herth formis of years o ce will depend onether this prblem can be solvd.地球上生命的来源没有人确切懂得地球是如何开始形成的，由于在很早此前它就形成了。然而，一种普遍为人们所接受的理论是:宇宙来源于一次大爆炸,这次大爆炸将物质投射到四周八方。然后,原子开始形成并结合成恒星和其她天体。大爆炸后好几十亿年过去了,但地球还只是一团尘埃。随后它会变成什么没人能懂得,直到38-4亿年前,这团尘埃才慢慢地

42、形成一种固体的球状物。地球(开始)变得剧烈动乱，不懂得这个固体形状与否会继续存在下去。它（地球)剧烈地爆炸喷出了烈火与岩石，最后产生了二氧化碳、氮气、水蒸气和其她多种气体，从而形成了地球的大气层。更为重要的是,地球冷却了下来，地球的表面就开始浮现了水。在火星这些其她行星上都浮现了水,但和地球不同的是,这些水后来都消失了。水会对生命的发展起核心作用，这一点在当时并不明显。诸多科学家觉得,由于地球上长期有水存在，使得地球得以把有害气体和酸性物质溶解在海洋里。这就产生了一系列的反映,使得生命就有也许开始发展了。好几百万年后来，水的表面开始浮现了极小的植物。它们繁殖起来就使得海洋布满了氧气,这为初期的

43、贝类及其她多种鱼类后来的进化发明了条件。接着，绿色植物开始出目前陆地上。随后，陆地上浮现了动物,其中有某些是昆虫,此外某些叫两栖动物，它们既能在陆地上生活,也能在水里生存。后来，当植物长大成了森林的时候，爬行动物浮现了。它们一般是通过孵蛋而繁衍后裔的。再后来某些叫做恐龙的巨型动物浮现了。它们也生蛋，在地球上生存了一亿四千多万年。然而,六千五百万年前,恐龙时代结束了。它们为什么会忽然灭绝至今仍是个谜。恐龙的灭绝使地球上哺乳动物的增多有了也许。哺乳动物不同于以往所有的生物形式，由于它们能从体内生产出幼仔并给幼仔哺乳。最后,大概60万年前,某些小巧聪颖、长着手脚的动物浮现了,它们散布在地球的各个地方。于是,她们接着成为了这个行星上最重要的动物。然而，她们对地球却不怎么在乎，她们把过多的二氧化碳释放到大气层中，这使得地球上的热不能释放到太空中去。因此许多科学家相信地球也许会因此变得太热而不适合生物的生存。因此，在将来的数百万年中,生命能否在地球上延续取决于这个问题能否得到解决。
