Unfortunately, the Earth is wiped out minutes before the question could be found. So, if you followed all that, the earth, in this series, was a computer, created by another computer which was created by a race of mice to discover the meaning of life. No more absurd, perhaps, than many, if not most, of our more earth-bound attempts to understand what it's all about. Not everyone, of course. Others, their meaning attached to money, and losing that, have gone out of their office windows.
Life has no meaning.
It does matter. It matters because we live our daily lives and conduct our personal affairs and the affairs of the world on the basis of what we believe the meaning is. What is of tremendous importance is whether we believe that whatever meaning we live by comes from the outside in or from the inside out. For the eons and for the billions of adherents of traditional western religion, Meaning comes from the outside in. Or, if you will, from the top down.
