Necessary Thing

No, it's refreshing that there isn't one. You see, almost any conversation we ever have on here with a theist is a thinly veiled attempt to shoehorn their personal woo into some sort of believable context. And we can generally see it coming a mile off every time. So it's great that isn't the case here. Yup, it's really sad. But that's what they mostly do, day in day out.

I agree that either everything is dependent on something else for its existence, or some things are (assuming our observations are reliable).

I don't personally think it's possible to go any further, perhaps ever. Knowledge extends as far as we can examine and test.

I would recommend delving into some quantum mechanics. If you've never looked at it before, I can guarantee you'll be amazed. It's incredibly bizarre and counter-intuitive. You have to try and abandon all your normal preconceptions about how things work. I've picked up only a very basic understanding, my current mental faculties being hampered by CFS make it hard for me to learn it as I perhaps once could. We have some guys on here who know a whole lot about it as well, if you're interested.
