One of the most interesting sites on the web is the “Astronomy Picture of the Day” produced by NASA. This website features a new picture every day, usually of objects in deep space with an explanation of the image. On August 18, 2019, there was a beautiful artistic rendition of a human with a star-filled background titled “Human as Spaceship.” (Because of copyright we can’t show you the picture, but you can see it HERE.) The opening line of the explanation is, “You are a spaceship soaring through the universe.”
The point of the presentation is that as we soar through the universe, we are not alone. We are the captains of our ships, our human bodies because we are not a singular living organism. There are a massive number of separate organisms that exist inside our bodies that do specific things for us. They help digest food, fight disease and infection, and carry vital materials on a liquid highway (your bloodstream) from one end of your body to the other. These organisms are the crew of this spaceship. They are bacteria, fungi, and archaea, and they actually outnumber your own cells. Science still doesn’t know what many of these organisms do, but they have their own DNA, and together they make up the human microbiome. You are a spaceship with a massive crew.
We sometimes seem to view God’s creation of the human body as a process similar to building a machine. To build a machine you would put together pre-manufactured parts in a prescribed way. To build a working and living human body requires a host of communities which do the jobs they were designed to do in ways that science is just beginning to understand.
Although space-travel movies are exciting and fun, they are not very realistic. Einstein’s theory of special relativity says that it’s impossible to travel at the speed of light. There is overwhelming proof that he was right. That fact has an impact on the reality of space travel.
Astronomer Dr. Hugh Ross wrote an excellent book entitled Why the Universe is the Way It Is. In this book, he states that due to the laws of physics the top speed of a spaceship would be limited to about one percent of the speed of light, or 6.7 million miles (10.8 million km) per hour. Based on that, he says that for aliens to travel from any other planetary system where intelligent beings could possibly exist would take at least 25,000 years! (Remember that it will take nine months just to travel to Mars, our neighboring planet.)
So when you watch a two-hour movie in which people travel from one planetary system to another at hyper-light-speed, remember that it’s only Hollywood. The reality of space travel is not what we see in the movies. We live in a universe designed by a Creator who gave us a special place with everything we need to live. Is there any kind of life, not just intelligent life, anywhere else in this vast universe? We don’t know, but the chances of meeting intelligent beings from another planet are very, very slim. That’s the reality of space travel.
By the way, my picture is poking a little fun at a statement made by the well-known atheist biologist Richard Dawkins in his book The Selfish Gene. He begins chapter 1 by stating, “Intelligent life on a planet comes of age when it first works out the reason for its own existence. If superior creatures from space ever visit earth, the first question they will ask, in order to assess the level of our civilization, is: ‘Have they discovered evolution yet?’”
So does discovering evolution indicate advanced civilization and the level of our intelligence? More importantly, does evolution explain the reason for our existence? Personally, I think the reason for our existence is not found in evolution, but begins in Genesis chapter 1 and is developed in the rest of the Bible.
