Here's what I learned in my 10 years in Sunday School combined with my understanding of the present scientific model of the universe.
As recently as 150 years ago, LOTS of people tried to count backward through the bible to discover the origin of everything. Pretty much that adds up to about 6500 years. Bah.
What a simple answer. Why would you want a simple God?
The bible as written in a much simpler time for a much simpler audiance. And while there are wonderful lessons to be learned in that book... It would be a mistake to take it literally.
Seriously... God is infinitely intelligent. Would he have just conjured up our existence out of wholecloth? *BAM* Adam, Eve, T-Rex, caribou, oil, Trump's hair. That seems a little simple for an omnipotent being don't you think?
An amazing rule of physics states that the more we know about an object's speed, the less we know about its location. And the more we know about an objects location, the less we know about its speed. This means that if we manage to pinpoint an object's exact location in time we know absolutely nothing about it's velocity and vice versa. The theory goes that if we could calculate both the speed and location of an object we would be able to predict its path, and how it will interact with other objects and their locations and velocities and so on.... In short, we'd be able to predict the future.
But as it stands we can't do either.
We can't even line up a cue ball and fire it off at an exact angle and velocity so as to sink every ball on the table in one shot.
Enter God. (Or random chance for you atheists)
Waving a magic wand and producing planets and stars... the universe as we know it... in one stroke is too easy... What a lazy God that would be.
This guy put all the matter of the universe into one pin-prick sized mass and fired the cue ball. Not only was he able to put every ball in the pocket (so to speak), he was able to know the exact velocity and location of every particle of matter he put into motion. And not only was he able to track what we can't in the wildest limits of theoretical physics... He did it like he was lining up the eight ball in the corner pocket. He put every sub-atomic particle in the universe into a specific motion. He calculated the exact trajectory, velocity and location of every sub-atomic particle in the matter that kicked off our existence to the point that he knew where and when hydrogen would form from quarks and muons and gluons and coelesce into stars that would eventually go nova and create helium that would coalesce into new stars that would collapse and super nova and would produce progressively heavier elements that would eventually form solar systems and planets... and eventually complex chains of carbon molecules that spontaneously divide into other complex chains of carbon molecules. Algae, amoebas, corals, vetebrates, mammals, us. All from one cue shot.
And what makes us so special? How is it that we are created in the image of God?
To this day we still struggle with the question of right and wrong. And that is probably an odd side track to our original purpose. (assuming that we are the end of the chain... or even had a purpose to begin with) Because on a grander scale we are trying to understand how this universe works. The result of a 15 billion year old cue shot is a group of fundamental building blocks that has achieved the ability to combine into complex groups and observe the world around itself and eventually, one day, understand that world.
And should we be the intended part of that cue shot to finally understand both how and why the universe is what, how, where and why it is... God will have achieved his goal in creating something in his image. A playmate... conversationalist capable of dealing on his level. Whatever you want to call it.
I guess you could say that God was bored and needed someone to talk to. Or lonely? I suppose it doesn't matter except to the person who is trying to rationalize his existence.
