A brief recap:
We’re in the midst of a new epoch in our human history, an epoch largely defined through the development of new technologies. While many of these technologies have advanced our ability to communicate across vast distances instantly and to devise new methods to improve our health and standards of living, they’ve also allowed scientists to dive far more deeply into the fundamental building blocks of our physical, chemical and biological worlds. And, along with these developments, we’re beginning to see early shifts in the most elemental and perhaps most important of all debates: “Is there actually a God.”
When up until recently, that discussion was relegated in large part to theologians and the practitioners of various religions, the possibility of its truth has not been seriously embraced by the broader scientific community for hundreds of years.
Then came the Big Bang and, all of a sudden, it appeared that there was actually a physical origin of the universe, before which there was no time or space or matter or energy. Yet somehow something came out of nothing. How did that happen?
Well, we can say everyone came to a kind of standstill, sort of like a heavyweight champion boxing fight. Each in their own corner, posturing, with no apparent bell to bring them together. The theists had their answer (God) and many scientists had theirs answer (Anything but God).
Now, let’s be a little more specific.
What has been proven conclusively (about which there is no apparent disagreement): All that we know that exists had a beginning. Before that, there was nothing. No thing. No matter (stuff). No energy. And, no time. No nature.
Then, in less than one trillionth of a second (in our time), there appeared everything that is now contained in our universe. All the stuff that we call galaxies (of which there are at least hundreds of billions) and all that is in them and between them. One trillionth of a second (let that roll around in your head) and “poof” the stuff that makes up approximately one billion trillion stars alone. That’s a billion times a trillion. Plus other stuff. From nothing to the actual physical amount of matter and energy that it took and continues to take to make that much stuff. Poof.
Just look out your window. See the trees and houses, roads and cars, people strolling. Then cast your mind’s eye further and see the mountains and forests and rivers and beaches and oceans that seemingly stretch forever. Whole continents come into focus and, then, as we look downwards, we can see all of the minerals in the earth until we reach our molten core. Just a short 93 million miles away is the natural source of the energy to sustain us, our own star, massive from our perspective but really not a blip on the cosmic radar. Somewhere around seven billion of us, with all other creatures, inhabit our planet that just happened to be structured exactly how we need it in order to sustain life.
That’s worth repeating. We live in a place and at a time that is exactly how it needs to be in order for us to be here alive.
Ok. That may seem to be a simple statement. As in, “of course. It has to be that way or else we wouldn’t be here. Why is that surprising?”
The prevailing viewpoint on this for most of the last century and going backwards into the 1800s was that we were basically lucky. For instance, we had a sun that was at the right distance away and could give us energy without burning us up. We had the right amount of gravity that kept us planted on the ground but not so much as to squish us flat. We have the right atmosphere that supports life: Right amount of oxygen, while also providing the right amount of CO2 to support vegetation. We have the right minerals, the most important of which is carbon that is required for life. We have water, which only exists in a very narrow range of temperatures in liquid form, without which life would be impossible. Carbon and water are the fundamental building blocks of life.
The advances in biology, especially evolutionary biology from about 1850 onward, suggested that natural processes led to the development of complex life forms, including the appearance of countless species. While Darwin and other evolutionary biologists freely admitted that they didn’t know how life emerged from non-life on our planet perhaps billions of years ago, they largely coalesced around a common hypothesis that ran something like this:
A pre-biotic (meaning non-life) “soup” of chemicals in young earth (our earth has been around for the most part for about four billion years) spontaneously reformed as biotic chemicals (hence the term “biochemistry”). A ton of research, thinking and experimental efforts have gone into considering what those chemicals needed to be and what mechanism would need to occur for them to reform from non-living to living.
In essence, they were trying to figure out how the first living cell was born.
While running the risk of being overly simplistic, the science texts always ran something like this:
Through some infusion of energy (lightning strike, heat, etc…), the non living chemicals transformed themselves into a simple living cell. This is the “primordial goo” that spontaneously became alive, then able to reproduce itself. Following that, nature took over through natural selection and random mutations that, with time, led to the complex life forms that now populate our planet and allow us to exercise such things as the ability to reason.
The fundamental precept (a presupposition) was that none of this was guided by any kind of intelligent and creative external force.
(Brief aside: Another theory, not taken particularly seriously by most scientists but offered up as a possible explanation, is that an alien life form “implanted” life on this planet, either by intention or accident. This is still bandied around today. However it doesn’t answer the question of how that life form originated in a universe of just matter and energy.)
It’s right here that the divide is at its most pronounced. Just as the question of how our universe spontaneously appeared from nothing, the question of how the first live cell came forth from non-living chemicals is fundamental to how we should address whether we are the product (result) of intelligent design or unguided and unintelligent “natural” processes.
If all of this is sounding too complicated or esoteric, consider that the answer to those two questions will impact everything we do, behave, and think about in the course of our lives. Yes, ultimately, the answers to those two questions is at the basis of everything.
Right here is where the rubber hits the road.
