Tip: You can use square brackets […] to truncate the quotation in order to make the reading more fluid and retain only the important passages.	It has been estimated that there are between one and thirty billion planets in our galaxy, and around one hundred billion galaxies in the universe. Removing a few zeros just to be on the safe side, a reasonable estimate of the number of planets available in the universe is one billion billion. Now, suppose that the beginning of life, the spontaneous appearance of a DNA equivalent, really was a completely staggering improbable event; so improbable that it only happened on one planet in a billion. A funding agency would burst out laughing if a chemist told them that the chances of their research succeeding were only one in a hundred. But here, we're talking about a one-in-a-billion chance. And yet... even with such an absurdly small chance, life will nonetheless have appeared on a billion planets, including Earth, of course. This conclusion is so astonishing that I repeat it. If the chances of life appearing spontaneously on a planet were one in a billion, even so, this staggeringly improbable event would occur on a billion planets.
