First off, the words in the dictinary are already arranged in order - by someone.
I hand you a Chinese dictionary, and a similarly-formatted list of randomized Chinese characters of equal length.
Can you tell the difference?
The meaning of the dictionary doesn't exist in the dictionary. It exists, or doesn't exist, in your head. Similarly, there's no "meaning" in DNA. All it does is put amino acids in a row, based on the laws of physics. We might look at genetic sequence and associate it with its protein product; in doing so we might say that the sequence
means that protein, but that is a mistake. The sequence
does that protein. It doesn't
mean that protein.
There's no meaning in DNA, therefore talking about meaning is a non-sequiter.
I find it more plausible that a massive infussion of intellegence was nessessary to both get it all started and to continously guide the process.
Yet this is impossible, because the only intelligence known to exist in the universe is human, and we weren't around at the time. Once we have eliminated the impossible, whatever remains, no matter how improbable, must be the truth.
But what's even better is that evolution
isn't improbable; in fact, it's inevitable. We know it happens because we observe it; but moreover, it's impossible for it not to happen.
