We Weren’t There. And it Matters Not.

“[God] stretches out the heavens like a curtain, and spreads them like a tent to dwell in.” (Isaiah 40:22, and ten other similar passages)

In his article, “What About Atheism & Agnosticism?” (The Lutheran Layman, (July-August 2014), p.3), Rev. Peter Kirby wrote with respect to the details of God’s creation, “No one was around at the beginning of the universe…to report on what happened.”  Kirby’s entire article can be read online at http://www.lhm.org/ layman/default.asp.  The implication of his statement is that the Lutheran Church-Missouri Synod interpretation of Genesis need not be reconsidered because science has nothing to say about beginnings.  Yet for not only biblical reasons, but also scientific ones, he is wrong.  Although his statement is obviously true, that fact is utterly irrelevant to his assertion that modern science is ignorant about the history of the cosmos.  As we shall see, God has so constructed the laws of His universe (specifically light-travel speed) that we have the capacity to view virtually the entire history of the cosmos from the vantage point of our time.  Consequently, we don’t need to have been present at its very beginning in order to observe what happened then.  For example, although I have never actually crossed the border from Israel into Syria, a few decades ago I had a broad unrestricted view across miles of its territory as I looked out from its boundary with Israel at the Golan Heights.  Similarly, the finite aspect of the speed of light makes it possible for us to look beyond the boundary of the present time, out into the past.  I invite your initial skepticism on this matter provided you follow me on these things.  I assure you that this is no trick.
 
We can only see the moon as it was; never as it actually is.  That is how our perceptions must always be except when we are viewing local objects.  For example, when we see either a friend sitting across the table or Mount Rainier on the horizon, we effectively observe these two objects in the present moment for the reason that they are nearby.  On the other hand, when we look upwards into the heavens we are always looking into the past.  The reason for this is that light does not travel at infinite speed.  Instead, it races away at 186,000 miles per second (which seems like infinite speed compared to a Corvette)!  Indeed such a velocity is the equivalent of 7 times around the world every second.  But, again, that journey is not instantaneous.  With respect to our view of planets, stars, and galaxies, light-travel realities mean we are only able to see these individual celestial objects after light from their surfaces has traveled the entire distance between us in order to finally reach our eyes.  Except from within our solar system, astronomical distances in “light years” are the measured lapse of TIME in years taken for the light to complete the respective journeys because, again, light travel takes time.
 

According to the above considerations, in round figures (pun intended) we see our moon as it was 1.25 seconds back in time, the Sun is likewise 8 minutes so, Jupiter 40 minutes, and our image of every star in the Big Dipper involves seeing them between 80 and 100 years back in the past (before most of us were born).  Peering out to the edge of our own galaxy (we are half-way out from the center) entails looking back to 25 thousand years ago, while the view of our nearest neighboring galaxy (Andromeda) involves seeing it as it was 2.3 million years ago, and so forth and so on.  Indeed the Hubble Extreme Deep Field photo (henceforth HEDF) reveals the primitive state of those galaxies at a much, much, younger universe 13.2 billion years back into the past (take a gaze at the image at http://en.wikipedia.org/wiki/Hubble_ Extreme_Deep_Field).
