Anyone who has “debated” with an uneducated atheist for more than, oh, 30 seconds, has heard the refrain spoken in a tone of triumph and challenge, “If God can be infinite, then why can’t the universe be infinite?”
Remember the good old days when atheist scientists actually believed that the universe had existed from eternity past? Then came background radiation, a rapidly expanding universe, low entropy etc. etc. etc. We now know that the universe had a beginning around 15 billion years ago. That hasn't stopped the desperate attempt to prove otherwise but - whatever.
What’s interesting though is how the atheist’s question of today is exactly backward. Instead of, “If God can be infinite, why can’t the universe be infinite?” the question should be, “If you, once believed that the changes in matter can be ongoing from the infinite past, why can't an immaterial, changeless, timeless Greatest Conceivable Being that we call God be infinite?”
That will elicit a response, "Well, I don't believe in God," However if God is real enough to make the first comment then He can be real enough to make the second.
. We know from scientific evidence that whatever BEGINS to exist has a cause.
. And we know beyond any doubt that the universe BEGAN to exist.
. Therefore we know that the universe had a cause.
We also know that our universe cannot have another universe or a billion universes or an infinite number of universes preceding it because:
. There cannot be an infinite regress of causes.
. Nor can the universe create itself nor precede itself, either materially or chronologically.
We also know that:
. Existing outside of time, the Cause is infinite or Eternal,
. Existing outside of matter, the Cause is immaterial or Spiritual,
. Existing as the Cause of time and energy, space, matter and the laws of physics, the Cause is immeasurably more powerful than the mathematically precise universe and its exquisitely Finely Tuned constants and quantities.
. The cause cannot be “scientific” because neither matter nor the laws of physics existed prior to the Singularity. (This by the way is a working definition of a miracle).
. Therefore the cause is not scientific but Personal.
. The transcendent Cause of the universe is therefore on the order of a Mind. It’s omniscient, omnipresent, and omnipotent.
. That Cause, at least in the West is described as God.
Atheist scientists are forced to a priori ignore this reasoning. No matter what the evidence, as long as it includes the supernatural, atheist scientists cannot allow themselves to examine the evidence. Is that logical? Is that reasonable? Is it scientific to leave out evidence that won't produce the results that you want?
That’s why, even if you happen to stumble upon an educated atheist, that person is forced to read, “Whatever begins to exist has a cause,” yet hear or interpret or simply deny by saying, “Well if everything has a cause, then God must have a cause.”
Without a word of a lie, atheists cannot see the difference between the two sentences. They simply cannot do it.
Reality is, if the world’s brightest scientists at one time believed that the universe / matter could be eternal, and without cause, they should have no trouble allowing that a Greatest Conceivable Being is also eternal and without cause.
Reality is, we now know beyond scientific doubt that the universe is not eternal, that it did in fact have a beginning.
Any conclusion that says otherwise cannot be reached in a scientific manner but must be reached by a priori philosophical stance and accepted as fact even though it is fallacious in nature.
