Carl Sagan sobre cómo comenzó todo

“In many cultures it is customary to answer that God created the universe out of nothing. But this is mere temporizing. If we wish courageously to pursue the question, we must, of course ask next where God comes from? And if we decide this to be unanswerable, why not save a step and conclude that the universe has always existed?”

[Carl Sagan, Cosmos, page 257]
