I don't need to invoke God in my explanation for the universe's origins because I can honestly admit that I do not know how the universe came to be, except that it did. And I am content to let that mystery remain, allowing the cosmologists to figure it out, if it is indeed knowable at all.
You seem to think that "God did it" is an intellectually superior explanation to "I don't know". It's not. Your explanation is about as satisfying as saying that it all happened by magic. In fact, your explanation is the same as saying that it happened by magic -- immaterial nothing created material everything.
Now, to my question: how can you speak of a time before the Big Bang given that you've earlier said that time was created at the Big Bang?
I have never in all of my posts spoken of a time before time.
But something must be timelessly eternal in order to have created time.
And whatever created the universe must also possess several other attributes besides this one.
Now we know this because of looking at what the universe is. It is spatial, hence the creator must be nonspatial. It is material, hence, the creator must be immaterial.
This of course is a logical and rational inference even if we do not know how to explain "how" this could be. The beauty of it all is that we do not have to be able to know how this entity could be all of these things, but we do know that the evidence warrants such a being exist.
Life as we know it, the universe and all that there is cries out that there is a creator, an intelligent Mind behind it all.
Science takes us to the point where we must leave her and use other disciplines pertinent to our position to understand how and why things are the way they are.
The whole point of this thread is to show that either path you choose requires an exercise of faith.
Faith that God created the universe is the rational and reasonable step in the direction of where the evidence leads us. Science cannot hold our hand when we make this step, but we must turn and say thank you to it for leading us this far.
Christians maintain that it is far more incredible to believe the universe just spontaneously self-generated itself. It goes against all reason and rationality to maintain this.
We maintain that it is far more reasonable for their to be a Creator who is the Greatest Conceivable Being who created the universe. It is also the most simple explanation for the data.
To maintain anything else requires incredible faith in hypotheses and metaphysical theories which have no scientific or philosophical grounds and which are at best, purely imaginative.
After looking at the evidence you either accept that it is extremely more plausible that God exists as opposed to Him not, or you maintain some other unscientific, ungrounded incoherent hypothesis as to why something exists at all.
If you hold the latter, then in it will be "inspite" of the evidence, not because of it.
It shall be an act of the will to choose an explanation other than God. And that, with no good intellectual reason.
And to do this would require great faith indeed. In fact it would be akin to you being a believer in scientism.
The Holy Scriptures time and time again tells us to look up into the heavens and witness the majesty and awesomeness of it all and know that God made it all. But some cannot allow God into "their " world. I find this most ironic and it serves only to show us that we really do have a choice and that we were fearfully and wonderfully made with the freedom to choose.
I hope and pray you choose Him my friend.
