There’s the light at the end of the tunnel. Then, after the train hits, there’s the light that you float toward.

That sounds fake, but OK. (Not the heat colors part, I know that part.) Isn’t the bulk of visible moonlight basically reflection?

Evolution argues differently against a law that is accepted EVERYWHERE BY EVERYONE. Evolution says that we started out simple, and over time became more complex. That just isn’t possible: UNLESS there is a giant outside source of energy supplying the Earth with huge amounts of energy. If there were such a source, scientists would certainly know about it.

> Depends on how technically picky one wants to get. The moon, like any object not at absolute zero, emits blackbody radiation proportionate to its blackbody temperature, in this case an [average of 270.7°K](http://nssdc.gsfc.nasa.gov/planetary/factsheet/moonfact.html). Humans can’t see this radiation directly and I doubt that’s what the Bible was referring to as the “lesser light”, but still, it’s there.

Since you brought up the theme of being technically picky…

Kelvins are an absolute measure, it’s nonsensical to label them as degrees.

Besides, didn’t we already have ‘do you know better than NASA’ in this thread? Your NASA cite doesn’t refer to Kelvins as having degrees.

Well the moon is sometimes a bright object depending on its phase. Sometimes it’s a new moon.  
Given that, it seems strange to describe it as a light that rules the night (especially in a context that implies like the sun lights the day), and stranger too why it wasn’t just made to be a light-emitting object…

Allow me, then, to nitpick with renewed vigor! 😉

You are incorrect. It isn’t “nonsensical” to label Kelvin units as degrees because that’s exactly what they were called – and denoted as such with the degree symbol – until the 13th General Conference on Weights and Measures which redefined the usage in 1967. Until then °K was the accepted usage, as in [this old paper](http://adsabs.harvard.edu/full/1930ApJ....71..102P) or [this more recent one](http://www.nature.com/nature/journal/v196/n4853/abs/196463a0.html), both of which use your alleged “nonsensical” notation. Moreover, the Rankine scale is also an absolute measure exactly analogous to the Kelvin scale, and still uses the “degree” nomenclature and symbol.

Finally, there’s a difference between sloppy typography, of which I was guilty as charged, and a fundamental error in physics regarding the emission of radiation from the moon. 🙂
