— Carl Sagan"I never said it. Honest. Oh, I said there are maybe 100 billion galaxies and 10 billion trillion stars. It's hard to talk about the Cosmos without using big numbers. I said "billion" many times on the Cosmos television series, which was seen by a great many people. But I never said "billions and billions." For one thing, it's too imprecise. How many billions are "billions and billions"? A few billion? Twenty billion? A hundred billion? "Billions and billions" is pretty vague. When we reconfigured and updated the series, I checked-and sure enough, I never said it."

Had I been present at the Creation, I would have given some useful hints for the better ordering of the universe. Remarking on the complexity of Ptolemaic model of the universe after it was explained to him. Footnote: Carlyle says, in his History of Frederick the Great, book ii. chap. vii. that this saying of Alphonso about Ptolemy's astronomy, 'that it seemed a crank machine; that it was pity the Creator had not taken advice,' is still remembered by mankind, - this and no other of his many sayings.

From the standpoint of our spiritual development, it might be important for us to realize that we came from an unknown somewhere; we brought with us an attained state of consciousness; and while we are here, we are expanding that consciousness. From some perspectives, it may seem that we are making giant strides, but from the greater overview, our quantity of spiritual knowledge is smaller than Ptolemy's knowledge of astronomy!
