地球上生命的起源

没有人确切知道地球是怎样开始形成的，因为在很早很早以前地球就形成了。然而，一种普遍为人们所接受的理论是；宇宙起源于一次大爆炸，这次大爆炸讲物质投射到四面八方。然后，原子形成并结合成恒星和其他天体。

大爆炸后好几十亿年过去了，但地球还只是一团尘埃。随后他会变成什么没人能知道，知道38-35亿年钱，这团尘埃才慢慢形成一个固体的球状物。地球开始变得激烈动荡，不知道这个固体形状是否会继续存在下去。它猛烈的爆炸喷出了烈火与岩石。最终产生了碳、氮气、水蒸气和其他多种气体，从而形成了地球的大气层。更为重要的是，地球冷却了下来，地球的表面就开始出现了水。

在火星这些其他行星上都出现了水，但和地球不同的是，遮羞水后来都消失了。水会对生命的发展起关键作用，这一点在当时并不明显。很多科学家相信，由于地球上长期有水存在，它使得地球得意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应，使得生命就有可能发展下去。

好几百万年以后，水的表面开始出现了极小的植物。他们繁殖起来就使得早期的海洋充满了氧气，这为早期的贝类及其他各种鱼类的发育进一步创造条件。接着，绿色植物开始出现在陆地上。随后，陆地上出现了动物，其中有一些是昆虫，另外一些叫两栖动物，他们既能在陆上生活，也能在海里生存。
