Last week was my oldest daughter’s 5th birthday in my mind the next “big” birthday after the always special year one. I decided on a geology themed day one of whose components were her, me and my younger daughter who’s 3 taking a trip to a local limestone cave that holds walk through tours.
Given that we were visiting the cave on a weekday we had the privilege of getting a private tour: just me, the girls and our very friendly and helpful tour guide. I was really hoping the girls would get to see some bats, which I figured would be hibernating by now. Sadly, the bats were gone. In some places upwards of 90% of them had been killed by an epidemic with the understated name of “White Nose Syndrome” a biological catastrophe I hadn’t even been aware of and a crisis both for bats and farmers who depend on them for insect control and pollination.
For a local show-cave this was pretty amazing- lots of intricate stalactites and stalagmites, thin rock in the form of billowing ribbons a “living” growth moving so slowly it appears to be frozen in time. I found myself constantly wondering how long it took for these formations to take shape. “We tell people thousands of years” our guide told us. “We have no idea how old the earth is”. I thought to myself that I was almost certain that we had a pretty good idea of the age of the earth – 4.5 billion, but did not press- too interested in the caves features and exploring with the girls. I later realized I should have, it would have likely made our guide feel more at ease.
Towards the end of our tour we spotted a sea shell embedded in the low ceiling above us, and I picked up the girls one at a time so they could inspect it with their magnifying glass. I felt the kind of vertigo you feel when you come up against deep time. Here was the echo of a living thing from eons ago viewed by the living far far in its future.
Later I found myself thinking about our distance in time from the sea shell and the cave that surrounded it. How much time separated us and the shell? How old was the cave? How long had the things we had seen taken to form? Like any person who doesn’t know much about something does I went to our modern version of Delphi’s Oracle- Google.
When I Googled the very simple question: “how old are limestone caves?” a very curious thing happened. The very first link that popped up wasn’t Wikipedia or a geology site but The Institute for Creation Research. That wasn’t the only link to creationist websites. Many, perhaps the majority, of articles written on the age of caves were by creationists, the ones that I read in seemingly scientific language, difficult for a non-scientist/non-geologist to parse. Creationists seem to be as interested in the age of caves as speleologist, and I couldn’t help but wonder, why?
Unless one goes looking or tries to remain conscious of it, there are very few places where human beings confront deep time- that is time far behind (or in front) of thousands of years by which we reckon human historical time. The night sky is one of these places, though we have so turned the whole world into a sprawling Las Vegas that few of us can even see into the depths of night any more. Another place is natural history museums where prehistoric animals are preserved and put on display. Creationists have attempted to tackle the latter by designing their very own museums such as The Creation Museum replete with an alternative history of the universe where, among other things, dinosaurs once lived side-by-side with human beings like in The Flintstones.
Another place where a family such as my own might confront deep time is in canyons and caves. The Grand Canyon has a wonderful tour called The Trail of Time that gives some idea of the scale of geological time where tourists start at the top of the canyon in present time and move step by step and epoch by epoch to the point where the force of the Colorado River has revealed a surface 2 billion years old.
Caves are merely canyons under the ground and in both their structure and their slow growing features- stalactites and the like- give us a glimpse into the depths of geologic time. Creationists feel compelled to steel believers in a 5,000 year old earth against the kinds of doubts and questions that would be raised after a family walks through a cave. Hence all of the ink spilt arguing over how long it takes a stalagmite to grow five feet tall and look like a melting Santa Claus. What a shame.
It was no doubt the potential prickliness of his tourists that led our poor guide to present the age of the earth or the passage of time within the cave as open questions he could not address. After all, he didn’t know me from Adam and one slip of the word “million” from his mouth might have resulted in what should have been an exciting outing turning into a theological debate. As he said he was not, after all, a geologist and had merely found himself working in the cave after his father had passed away.
As regular readers of my posts well known, I am far from being an anti-religious person. Religion to me is one of the more wondrous inventions and discoveries we human beings have come up with, but religion, understood in this creationist sense seems to me a very real diminishment not merely of the human intellect but of the idea of the divine itself.
I do not mean to diminish the lives of people who believe in such pseudo-science. One of the most hardworking and courageous persons I can think of was a man blinded by a mine in Vietnam. Once we were discussing what he would most like to see were his sight restored and he said without hesitation “The Creation Museum!”. I think this man’s religious faith was a well spring for his motivation and courage, and this, I believe is what religions are for- to provide strength for us to deal with the trials and tribulations of human life. Yet, I cannot help but think that the effort to black- hole- like suck in and crush our ideas of creation so that it fits within the scope of our personal lives isn’t just an assault on scientific truth but a suffocation of our idea of the divine itself.
The Genesis story certainly offers believers and non-believers alike deep reflection on what it means to be a moral creature, but much of this opportunity for reflection is lost when the story is turned into a science text book. Not only that, both creation and creator become smaller. How limited is the God of creationists whose work they constrict from billions into mere thousand of years and whose overwhelming complexity and wonder they reduce to a mere 788,280 human words! With bitter irony creationists diminish the depth of the work God has supposedly made so that man can exalt himself to the center of the universe and become the primary character of the story of creation. In trying to diminish the scale and depth of the universe in space and time they are committing the sin of Milton’s Satan- that is pride.
The more we learn of the universe the deeper it becomes. Perhaps the most amazing projects in NASA’s history were two very recent one- Kepler and Hubble. Their effects on our understanding of our place in the universe are far more profound than the moon landings or anything else the agency has done.
Hubble’s first Deep Field image was taken over ten consecutive days in December of 1995. What it discovered in the words of Lance Wallace over at The Atlantic:
What researchers found when they focused the Hubble over those 10 days on that tiny speck of darkness, Mather said, shook their worlds. When the images were compiled, they showed not just thousands of stars, but thousands of galaxies. If a tiny speck of darkness in the night sky held that many galaxies, stars and—as scientists were beginning to realize—associated planets … the number of galaxies, stars, and planets the universe contained had to be breathtakingly larger than they’d previously imagined.
The sheer increased scale of the universe has led scientist to believe that it is near impossible that we are “alone” in the cosmos. The Kepler Mission has filled in the details with recent studies suggesting that there may be billions of earth like planets in the universe. If we combine these two discoveries with the understanding of planet hunter Dimitar Sasselov, who thinks that not only are we at the very beginning of the prime period for life in the universe because it has taken this long for stars to produce the heavy elements that are life’s prerequisites, but that we also have a very long time perhaps as much as 100 billion years for this golden age of life to play out, we get an idea of just how prolific creation is and will be beside which a God who creates only one living planet and one intelligent species seems tragically sterile.
To return underground, caves were our first cathedrals- witness Lascaux. It is even possible that our idea of the Underworld as the land of the dead grew out of the bronze age temple complex of Alepotrypa inspiring the Greek idea of Hades that served as the seed through which the similar ideas of Sheol held by the Jews and revved up by Christians to the pinnacle of horror shows with the idea of Hell.
I like to think that this early understanding of the Underworld as the land of the dead and the use of caves as temples reflects an intuitive understanding of deep time. Walking into a cave is indeed, in a sense, entering the realm of the dead because it is like walking into the earth’s past. What is seen there is the movement of time across vast scales. The shell my daughter’s peered at with their magnifying glass, for instance, was the exoskeleton of a creature that lived perhaps some 400 million years ago in the Silurian Period when what is now Pennsylvania was located at the equator and the limestone that was the product of decay the shells inhabitant’s relatives began to form.
Recognition of this deep time diminishes nothing of the human scale and spiritual meaning of this moment taken to stop and stare at something exquisite peeking at us from the ceiling- quite the opposite. Though I might be guilty of overwinding, it was a second or two 400 million years or perhaps one might say 13 billion years in the making- who couldn’t help thanking God for that?
