Learn from history.

Christianity will eventually find itself on the pile of long
forgotten religions. There it will stand alongside others such
as Egyptian, Norse and even Greek Mythos.

I occasionally think about how arrogant the human species has
become. To simply declare the current beliefs to be the only
'valid' ones and all other lines of thought casually dismissed
as uninformed ( and therefore damned ) heathens.

Then I recall the species has been doing this since we first
walked the Earth. Apparently we still haven't quite learned that
lesson yet. :|
