It has always been evident right from the Old Testament that much of the religion
that is now so prominent was taken from the ancient world. Iraq once had the
world in its hands and the fire story and flood story and so on came from those areas
of the globe.
In addition the early church took the best of the best and adopted tradition and of
course they outlawed the other religions to ensure there would be only one official
living god and saviour. The truth always has a way of cropping up and challenging
the current belief system. I sometimes wonder what the future will determine about
our lost civilization.
