英语翻译
The fact that you and are alive is a statistical probability,and nothing more.The Universe was created (perhaps failed an infinite number of times before creating the Universe we see today) with the precise physical constants that were needed to allow the creation of Stars.In so many of sciences most fundamental equations there are constants that we are unable to explain,constants that represent Universal facts.A simple example would be π= 3.14159265… Why?One of the most important examples however is the gravitational constant G = 6.67300 × 10-11 m3 kg-1 s-2 used in Newton’s law.If this,along with many other constants,were different in any way the Universe would look completely different,it may not even exist.
你存在的事实是个统计概率,仅此而已.宇宙被创造时(也许创造前已经失败无数遍)拥有了创造星星的精确物理常量.在许多科学最基本的方程会存在我们目前无法解释的“宇宙常数”.举个简单的例子；π= 3.14159265…为什么?最重要的一个例子之一是牛顿重力常数6.67300×10-11不断观kg-1 m3 s-2.如果这些数字,连同其他常数,要是小或大一点点的话,我们宇宙会长的完全不一样,说不定,它根本不存在.
The probability that a Universe be created with these exact figures is so small,it is difficult to imagine.But if we assume that Universes are constantly being created,it becomes inevitable that this one became a reality.However,now we look at the probability of life being created in such a Universe.Though we cannot count the number of stars in the Universe,it has been estimated that there are approximately 1,000,000,000,000,000,000 or 1 billion billion.Let's assume that each star has 5 planets orbiting it.To our knowledge,we are the only intelligent life so the probability of having life in this Universe becomes 1 in 5,000,000,000,000,000,000.
一个宇宙创造时拥有了这些精确数字的可能性是如此的小,很难想象.但如果我们假设宇宙是不断地在被创造的话,我们宇宙能够存在就会变成一件不可避免的事.现在要看在我们这样的宇宙中,生命能够创造的概率是多少.虽然我们无法计算宇宙星星的正确数量,据估计约有1,000,000,000,000,000,000个或10亿10亿.接下来我们假定每个星星有5个行星在轨道.据我们所知,我们宇宙当中唯一有智能生命的行星就是我们地球,因此,能创造生命的概率是1/5,000,000,000,000,000,000.
Now let’s look at life on Earth.Right now,there are approximately 1.4 million different species,not including ones that are already extinct or one that we have not found yet.I think it is fair to raise this to 2 million (though I personally think 14 million would be closer to the truth),so the probability of humans being created is 1 in 2 million.
现在让我们看看地球上的生命.现在,大约有140万不同的物种,不包括那些已经灭绝或我们还没有发现的.我认为这个数字可以提高到200万(虽然我个人认为1千400万会更加接近事实),因此人类能够在地球上创造的概率是1 /2,000,000.
我是英国人，我的英文（应该）没有问题 :-)
请帮我看一下我的中文翻译。

稍改了一点,你看看怎样.

你和你的存在事实仅仅是个统计概率.宇宙由精确的物理常量创造而成(或许在创造出我们今天看到的宇宙前已经失败了无数遍),这些物理常量允许了恒星的产生.在许多科学最基本的方程中,存在着我们目前无法解释的“宇宙常数”.举个简单的例子：π= 3.14159265…为什么?最重要的例子之一是牛顿重力常数 G=6.67300×10-11 m3 kg-1 m3 s-2.如果这些数字,连同其他常数,要是小或大一点点的话,我们宇宙将完全不一样,说不定,它根本不存在.
