Bianca asked:

Why is it impossible to say how religion began?

===========

Perhaps you could resend this question in a more precise form. As it is, it seems awfully trivial. How
did building houses begin? How did horse-riding begin? How did making clothes begin? How did
asking questions begin? Without a time machine, it is impossible to say how any of those began,
because there were no records made of their beginnings. Now that we have newspapers, computers,
cameras, even books, that sort of thing, we can say when things began. But before all that...?
