I'm not a professional philosopher, but I took a liberal arts concentration in philosophy (maybe 4 or 5 university classes) in my undergraduate days, which included "Philosophy of Religion". I studied Thomas Aquinas, Martin Buber, C.S. Lewis, and various other writers, reading their words. I had read some Scientific Creationist literature as well, though this was so long ago I don't remember the authors.
However, I had encountered even more Apologetics online, though usually not of quite as high a degree of philosophical quality. But I've heard and considered many different approaches to justifying the view that God exists, and none have been convincing.
