Well your opinion that nothing existed before the big bang - OR - everything in the universe just suddenly miraculously spontaneously appeared out of nothing requires a far bigger religious leap of faith than anything I've said.
It doesn't actually; but here, with this "pot-kettle-black" argument, you are reinforcing what I said: that your position is religiously derived, and that you ARE talking about God. That's all right; I don't mind talking about God in a religious forum. I just mind that you pretend you're not doing so.
The reason it doesn't require more "faith" is that I'm not saying what you think I'm saying. I'm not saying "everything in the universe just appeared out of nothing." There was no nothing. There was no "was." Time has a boundary. There is no before the big bang, because "before" implies time stretching back further than that boundary. This isn't "faith," it's an ability to stretch the mind to encompass the totally unfamiliar and non-intuitive. That time has a boundary (two boundaries maybe) is not the way we experience time on an everyday basis, so it's HARD to think of it that way, but it doesn't require "faith." It just requires extreme flexibility of the imagination.
However, I have not been arguing from a religious or spiritual perspective any more than Spinoza or Einstein were arguing from a religious or spiritual perspective. To completely blow off those great scientific minds and declare them or their theories irrelevent to the discussion seems a bit arroagant to me.
Oh, I'm certainly not lacking in arrogance, but I'm not saying that they are irrelevant to the discussion. I AM saying, though, that the things you are quoting them as having said DO come from a religious or spiritual perspective. Einstein was an atheist and was hardly religious in any conventional sense, but he was deeply spiritual.
The thing is, he did not allow his spirituality to intrude into his science, anymore than he allowed his left-wing politics to do so. All of his scientific papers followed the rules exactly. The quotes you have presented by him do not come from any scientific papers. They represent Einstein as a person, but not Einstein as a scientist.
