Experiments have not shown there to have been an Adam and/or Eve. 1 - zip.
lol...
He specifically related it to evolution, I answered in that context.
If the bible lies about Adam & Eve, then...

Now you have to wonder about that Nothing -> Something -> Nothing idea... If it was really "nothing", then how was something created?
I can imagine it as something like a half full water balloon. If you hold it upright, all the water flows to the bottom. The top now has "nothing". If you flip it over, the top has "something" and the bottom has "nothing". If you applied that to the universe, you could guess that matter may be disappearing (to a place we dont know of), and our universe would have "nothing". That matter still went somewhere though, so in the big picture it isn't really "nothing".
Matter is here for one reason. Not enough antimatter. I am definately not a physicist but particles briefly pop into existence all the time. They come from "nothing" only to be cancelled out by the anti. Imbalance is why we are here and I have no doubt that the universe will again achieve balance and be "nothing".

I knew that would be taken wrong when I typed it.
The "lol" was to this "Experiments have not shown there to have been an Adam and/or Eve. 1 - zip." cause I thought it was a funny statement

Well, in terms that most of us can understand, matters do pop into existence, and so do anti matters, therefore canceling each other out. In the case of black holes, when these pair come close enough, and one of the element got sucked into the black hole (crossing event horizon), the remaining matter got ejected, and float back to the horizon of the universe, wherever that might be.
As for time goes, I don't exactly remember the details, but basically, the universe could very well be bouncing back from the "big bang" into a big crunch, and once again, nothingness. But, our current law, as stated, doesn't allow for something to be created out of nothingness, hence the theory of imaginary time.

That's an interesting read
Even if everything goes back to the moment of creation, everything inside the "space foam" is still something, not nothing.

Black holes really don't have anything to do with what I said. I posted a link earlier that black holes do indeed follow the laws of conservation of matter and energy.
Given that we are expanding now a "big crunch" is very unlikely. We will continue to travel until everything decays. Although we won't be here to see it.
You said in your first statement that matter does appear out of nothing but then in the last said it can't. It is the imbalance between matter and antimatter that allows us to be here.
I'm just pointing out what it is that we have learned, we have proven that matters do pop in and out of existence, from nothingness; our current scientific calculations do not allow for an equation to be created from nothing. So, in theory, we don't really know jack, or perhaps we need to come up with another way of calculating.
About black holes, most of the models I see, or portrayed has a plane (pass that plane is passing event horizon) and from there on everything would just be stretched and compressed until achieving singularity (or a parabola shape end of the black hole). So in theory, you can come really close to the sigularity of the black hole without passing event horizon, by not approach it from the front, but from the side?
