Traditional Church (not Christian as Christ did not teach this) belief was that God had created everything in 7 days as described in Genesis and biblical scholars had worked out that this had happened about 4000 years ago.
The advent of Geology as a science and Darwin's theory of natural selection requires an immense amount of time for the species we see around us today to have come into being by small changes to species that existed in the past.
Thus in effect Darwin said that the Earth is far OLDER than the bible says, and that species were NOT created as described in Genesis but that they evolved from life that existed in the past.
This was a direct challenge to Church doctrine and the Church is still trying to recover from it because when people looked at what Darwin had said and tried to disprove his theory they have so fat not been able to do so.
