By quantum uncertainty, a seed for the cosmos is bound to pop up from the void sooner or later. In any case, God was always there and He created the universe from nothing.
No. Where there is nothing, there is no quantum anything.
When did God decide to create the universe? Why didn’t He decide at an earlier time, so that at the time of Christ, people could have had access to computers and the internet? In that way, the Chinese and Japanese people would have known about His Son and they would have been able to be baptized of water and attain eternal salvation.
If he had decided to do so at an earlier time, you would have asked why he didn’t do so at an even earlier time. In fact, he did reveal himself to us in the very beginning of our existence. Baptism is the normal means of salvation, but it is certainly not the only one and those who did or do not know of Christ have no sin for not accepting what they did or do not know.
Who knows if we would even have computers and the Internet had the timeline not proceeded the way it did, with Jesus coming and dying when he did. And isn’t analog photography and video enough for you? Or perhaps the current Internet and computers are not enough- What about holographic video or a neural-link? You think that people would accept the truth if it popped up on their screens, but many people today don’t accept the truth about even much simpler and provable matters.
That said, this has nothing to do with creation exnihilo.
I think that most atheists would disagree with you. Inasmuch as atheism is simply a rejection of theistic claims, there is no requirement for them to come up with an alternative explanation just because they reject the God claim. Most atheists would argue that theists need to demonstrate that God is necessarily the only explanation for the existence of our universe. Until that is done, any claim that God is a sufficient explanation is useless.
Most people would disagree with this. Theism has always been and continues to be the default position for most of humanity. And though I went through a lot of learning and thinking to get to where I am now, I can reasonably say that there is far more evidence for the existence of God than for his absence. I think most people know that intuitively. Historically, democratically and intuitively, atheism is the position which holds the greater burden of proof. That said, as you no doubt know, there are many arguments, both classical and new, for the existence of God, which, whether you agree with them or not, are at least reasonable.
Ultimately, it doesn’t really matter which one holds the burden of proof for others. It only matters which one you will hold to the greater- and perhaps unreachable- burden of proof. The one who benefits or suffers form this is you…
And this has still nothing to do with creation exnihilo.
So, here goes:
Creation exnihilo is possible because God does it.
Here’s another question:
How could anything always have existed?
I look forward to theological and philosophical speculation on these questions, but I suspect that they cannot be definitely answered from this side of eternity. I’ll give you the classic (though overused) response that some learn to appreciate, while others don’t: It’s a mystery. Because it really is.
