The main problem with the question
Does God Exist? is that there are different ideas about what God is or could be. So I will examine multiple conceptions of God, not just one. If none of them stand up, then atheism will be justified, but if a single idea of God does stand up, even if all the rest fail, then some form of theism is justified, though it may be different from the theism you are accustomed to.
This post is for a video I made in 2011. I actually got answers from someone today, and I realized it would help to have a list of the questions asked in the video for my own reference, if nothing else. It may also prove useful to someone answering the questions.
