Rare Earth; compared to others (Introduction)
DAVID: The source of this latest claim that the Earth is very special is in this article:-http://blogs.discovermagazine.com/d-brief/2016/02/22/earth-is-a-1-in-700-quintillion-ki...-"A new study suggests that there are around 700 quintillion planets in the universe, but only one like Earth. It's a revelation that's both beautiful and terrifying at the same time."-Or maybe even 750 quintillion. Or even 800 quintillion. If only we could see the ends of the universe, we could actually count the planets one by one, couldn't we? Oh, the excitement! But even though we haven't a clue how many, or what those we can't see might be like, I'll go along with our being special. And I can't help feeling that 700 quintillion dramatically reduces the odds against our being lucky too. Alternatively, fancy God having to create 699 quintillion, 999 burble burble zeros and 99 planets just for our sake. Incredible, wouldn't you say?
