Proof God Exists & Why Create Us?

One way of proving that God exists begins by asking, "Can we demonstrate how God is the first cause needed for all that we perceive to exist?"

We can do this by using reason and logic, and the scientific evidence of observations of our Universe. Let's see ...

A. From ancient times, there has been a debate about whether the Universe is either Created or Eternal. But in the 20th century, astronomers discovered that the Universe is expanding. This is confirmed by the telescopes that were launched into space. This means that the Universe had a beginning, and if you imagine running it backwards you see that it goes back to what we call the "Big Bang." Thus, it is Not Eternal. And those same telescopes have also seen galaxies and stars that are much younger in the far distance (which is also the distant past).

B. So, if it began, we have to ask whether the Universe had a Cause, or was it Uncaused. But, by any verifiable scientific theory, the very thought that it could be uncaused is fundamentally absurd. There is no way for anything to come out of nothing. "Hawking Radiation" requires the event horizon of a black hole, and it slowly evaporates the central mass as it radiates. Even "quantum foam" needs the fabric of space itself for it to bubble into, and then it quickly annihilates itself. So we need a first Cause for the Universe itself.

C. Further, anything which has no cause would have to be self-sufficient and self-sustaining. But we know that the Universe is subject to the laws of thermodynamics, and has an inherent, irresistible tendency toward entropy. It will eventually run down and cease to function, and parts of it will stop long before the end. So it still needs something to sustain it, just to keep it in existence. That is yet another reason to deduce that it must have had a Cause from before the beginning, and could never have started itself.

D. Now, by what we know about the early Universe, right after the Big Bang, the fundamental constants that make the Laws of matter, space and time did not exist until after they themselves unfolded from that first colossal emergent event. Even our best theoretical physicists have no idea how those evolved. They just happened, and the Universe coalesced as a result. But why is that even important? Because it shows that the first Cause of everything must be timeless, spaceless and immaterial, and able to effect all of those fundamental laws.

E. After that, we observe that there two kinds of causes: Natural and Personal. By definition, natural causes require scientific explanations based on the laws of physics or biology. But before the Big Bang, there were no such laws. No gravity, no strong or weak atomic forces, no electromagnetism, no biology, or anything else. Even light had to wait. But Personal causes only require that someone chooses to do something.

F. However, Persons always act within relationships, and there are two kinds of relationships: subject/subject, and subject/object. Subject to subject interactions work by volition and response. And subject to object interactions work by imposing intent upon material inertia, to create difference. Without that difference, or distinction, everything would just be one messy clump without any meaning. But we can observe distinctions and differences, and impute a variety  of possible meanings to what we observe. So we know that there is a real subject/object relationship, which allows the Personal Cause to create.

G. So, let us summarize what we know by logical reasoning and scientific research to describe the attributes of this necessary Cause. It must be:
     1. Uncaused
     2. Self-sufficient
     3. Self-sustaining
     4. Timeless
     5. Spaceless
     6. Immaterial
     7. All Powerful
     8. Personal

H. This list of attributes is virtually the same as that which almost everyone has agreed is the basic description of God. Which leaves all of us with a, perhaps difficult, task -- to choose a belief system which accepts the necessity of recognizing a God who created our Universe.

So we have arrived at our conclusion:
The Universe exists, therefore God exists.
Q.E.D.

Our next question is closely related:

"Why did God create us?"

"Why" questions are a bit different from "How" questions. We have to look deeper. This question finds its answer even before the Universe and time began. It rests upon the very nature of God Himself.

A. God knows from personal experience how to relate to other persons. He is three, distinct but not separate, persons, sharing the same coextensive substance.

B. God has been eternally interested and involved with Himself, interacting via his triple persons, so intensely that His joy and love overflows with abundance.

C. All of God's actions are meaningful, and for any action to be meaningful, it must have a purpose. So by consensus in one accord, they sought to expand the divine communion by creating more persons to share with.

Step by step, God thought through the process for doing this.

D. God wanted to create something that would have initiative, and be interactive and meaningful.

E. Inanimate objects are of limited interest, as lacking any initiative to interact.

F. Only life can act with initiative and interact together, to seek food for survival and to perpetuate the species.

G. Even advanced animal life lacks depth of meaning. Mere cleverness is enough for them to accomplish their tasks.

H. Only fully self-aware Persons have sufficient initiative to interact together in thoughtful accord, and thus seek to create meaning for doing that. So God chose to make new beings much like Himself.

I. God decided to create a Universe which would be amenable, via natural laws of evolution, to the eventual creation of self-aware Persons. Its worlds should function mostly by mechanics, but allow for some interaction for guidance toward the right kind of creatures.

J. Thus apparently, God desired to create human kind, so that there might be an abundant society of self-aware, thoughtful Persons with whom the Divine Trinity could relate and converse.

K. Apparently, when there is no input from any outside source, even perfection can value further variety and novelty, even if just as an open horizon whereby it may share itself more widely.

Subsequent conjectural notes:

L. One can assume that the Heavens are home also to a variety of other species on other worlds, which also evolved because of the divine intention to create ever more persons to share with. That is why the Bible speaks of Angels, who sometimes help us. And unfortunately, we hear also of Demons, who apparently disagreed with the idea that a Trinity God should be the One in charge of everything.

M. Also according to tradition, the chief demon, Lucifer/Satan also disagreed with the decision to raise the human species to full personhood, on the grounds that we would never be obedient enough to be worthy of Heaven. So he tried to derail our development by introducing the concepts of good and evil too early, expecting us to fight among ourselves, before our capacity for faith was fully ready. Today, we know about Satan, because he is still trying to derail our development. In fact, he is known as The Greatest Deceiver, and goes by a few other aliases, too.
