The simplified presentation of an apologetic theist: "I have faith in something else that makes God a necessity."
Examples of "something else" include, but aren't limited to:
- A universe that could only be created by an external agency.
- Complex life that could only be intelligently designed.
- Objective and absolute moral values that exist in some way independent from those who value them.
- An external meaning for life/existence/them personally.
Apologetics isn't so much a defense of faith, just a displacement of it.
