Your problem is I wasn't raised by Christians.

Your second problem is I consider theism because I'm actually very studied on the issue, and have debated for over 20 years.

Side note: singularities are already theorized to be at the center of black holes and are perceivably of infinite density. It could just as well be the case that the Big Bang was the contents of our "current Universe" all contained in a single dominant black hole that reached some sort of peak mass and collapsed. Just a theory I pulled off the top of my head, but it's already stronger than any God theory as it's backed by at least some scientific data.

So...where was the black hole located, or "what" was it in?

There is no evidence supporting a god

Actually the evidence is all over the place. I've done this debate a hundred times. You're welcome to look through any of them.

The fact that you're willing to settle for "some unknown explanation"

I haven't settled on anything. I can tell you more about what the greatest atheist debaters have argued than 99% of Atheists. I get in debates and expect to see the best atheist arguments, because surely they are familiar with Hitchens and Dawkins, but nope, they don't know the arguments. The point? Closed minded Christians don't listen to 3 hour interviews with militant atheists. I have.

As for you? I highly doubt you can tell me the talking points of someone like William Lane Craig, a world reknowned theist debater. Is that what open mindedness looks like? I think not.

The problem with most atheists I come in contact with is they are linear thinkers, which means they are handicapped when it comes to thinking in or understanding nonlinear arguments. They typically just get lost. And then the name calling begins, they get mad, and I move on.
