Why are apologetics necessary? I was thinking about that today. My take is that they are necessary to defend the indefensible and to maintain a magic mindset. When religion and science collide the normal person off the street may start to question. So up pops the apologist to explain things away using circular logic and pseudoscience so the lay person can feel good about their religion again.
If a religion is true it should stand the test of time and should not conflict with science. That is, it should not conflict with the geographic record, the archaeological record, biology,etc.
As I have said before, if God hides things he is a trickster and not worth worshipping.
