“If you were an alien that was looking down on the earth and seeing what’s happening there and trying to explain it in order to explain everything that happens on earthin order to understand stuff that happens on earth, they would need to know everything. And let’s suppose that these aliens are so different from us, there’s nothing familiar about us.”
“Biological evolution can’t reach places that are not reachable by successive improvements, each of which allows a viable organism to exist.”
