We can be assured that there are only three possibilities as to how our universe, which everyone can readily see, got here. Let's briefly describe those three.
(1) It somehow emerged from nothing. When there is nothing, that means nothing. No matter, no energy, no space, no time, no magnetic forces, no radiation. This is something of which human's cannot conceive. But to rational man, there is only one way it could have happened and that is by some force which is not subject to the natural laws under which we exist. The "Big Bang" theory requires that everything did begin from nothing. An absolutely ridiculous assumption without acknowledging some supernatural source. And if you agree to that, there's God!
(2) The universe, in some form or another, has existed forever. Eternally. This is easy to eliminate because the universe (and matter) is in a constant state of irreversible decay. It makes no difference what some scientists may venture to say it would have taken one hundred billion to the 1,000 power years for full decay to occur. Eternity exceeds that millions of time and then some, infinity. Energy would long since have been rendered totally dispersed and unrecoverable. Besides, the naturalist scientists have now moved the existence back to some 14 billion years (in order to meet their need for things to have the odds of their evolving to be more believable). And they have no possible way of proving that.
(3) The universe was planned and created by an omnipotent, omniscient Spirit God, who is not physical in any sense, but spiritual which does not decay, does not age or die. The first argument about that from the naturalist is that it is not possible under our natural laws!. True, we acknowledge that. But the two possibilities listed above, are dependent upon something that circumvents our natural laws also. But, with all of this said, is it more logical that some supernatural accident occurred, or that there is a being who is capable of creating such?
Those who would vehemently deny such, not only have to admit they don't have any other answer, but they have to admit that they simply do not want to submit to a superior being and live by His instructions.
For those who would consider themselves fully knowledgeable of mathematical equations plus quantum math and mechanics and will try to prove the non-existence of God by such, and the means for things to have originated, I have a very lengthy article I hope you would read and try not to be so foolhardy sure of yourself before doing so. This article by Dr. Walter L. Bradley writing for the LeaderU.com web space. Here is the link to it:

Another factor concerning the "Big-Bang" supposition, those who support this figment of man's imagination are not trying to say that all this massive universe was extant at the time, just simply pressed into the "singularity". But regardless of what they say in that respect, from absolute nothing or all matter compacted into a single point, or "singularity", it won't hold up.
Aside from our three laws of thermodynamics, we also have a law which says that anything at rest (totally still), no activity whatsoever, will remain at rest until some external force causes it to move. Again, we are faced with an almighty and all wise Spiritual God who has the capability of transcending natural laws, which He created in the first place.
Then we have those who try to stay away from submission to God, who will say that there indeed may be some supernatural force or perhaps even a God who did set all this in motion, but they refuse to accept the biblical God, Jehovah. They base this on the fact that a good God would never have created such a mess which causes suffering and death. That he would have created a planet which could be entirely populated instead of so many uninhabitable. These are simply extensions of being unwilling to submit to God. There are perfectly sound answers to their questions if they would only listen.
