I don't think that calling the Singularity a "dot" is a sign of some mental or educational deficiency. From the standpoint of our universe it's a pretty apt description. After all, how would you call a state with no time, space, not even natural forces, let alone matter. Well, I know, singularity. But "dot" IMO will do too. I would say that Jeff was on his way out and simply chose (maybe instinctively) to hit "the bad atheist" where it would hurt the most -- your pride in intellectual and academic prowess.

Yes/no questions (if they are not clear paradoxes) can be answered as yes or no. When I ask such a question, I always want a clear-cut answer. I want the person to take a clear stand and proclaim it. I expect that that is in turn also the case when I'm asked such a question (whatever the reasons may be).

Jeff's questions were very personal -- "can you explain to your own satisfaction" etc. I suspect you could not answer "yes" because incompleteness (or even relativism) of scientific explanation does not satisfy you and you also didn't want to give Jeff a possibility to fire back by answering "no". No big deal in my book. It's the way you chose to handle it and that's that.

But as you may know I subscribe neither to your godless universe nor to Jeff's concept of God and most of what goes with it. Did it ever occur to you that you might be clinging to your ideas the same way Jeff is clinging to his? (And yes, from my point of view you are both mistaken.) Anyway, I just wish you both could see what I see. Then neither of you would have problem with modern science as it is and what we call God respectively.
