If you're going to argue that abiogenesis is not science, it might help to define science first.

Science is the formulation of natural explanations for observable phenomena in the universe. Abiogenesis (the emergence of life from non-life), while not yet observed itself, is a natural explanation for the observable phenomenon of life. It is therefore a scientific hypothesis, and yes, it is science. What it is not (yet) is a theory.

Though some natural selection may have occurred in the process, abiogenesis should not be classified as chemical evolution. It may have been a rapid, non-cyclical process instead. We freely admit that we have no clue how it happened.

At least until we do observe a second abiogenesis in a lab or in nature (positing that the event which produced us was the first), not only do we stick to speculation as to how it happened, but we refrain from stating 100% certainty that it did happen. If evidence of intelligent design were to emerge (say, actual physical impressions of fingerprints in our DNA) we would soon abandon the hypothesis that we are the products of abiogenesis. We would then try to determine whether the designer was a god, an alien or an extinct Earth creature, and in all three cases start to hypothesise about the abiogenesis and evolution of that being, if any.

This is the difference between a scientific hypothesis and a faith position. We assume a scientific hypothesis for practical purposes as the best current explanation until a better one comes along, at which point we chop and change. We're not precious about it at all, at least until it accumulates enough evidence to be declared a theory. A man with a faith position defends it to the end, because he usually expects no contradictory (or even supporting) evidence to present itself.

Another difference is that a hypothesis must be falsifiable, which means there must be some hypothetical event which demonstrates it is false. Our abiogenesis is falsifiable because we might find firm evidence of a creator, like a signature or a work log billions of years old. By comparison, what would falsify the intelligent creation of life? Nothing. Even if we achieved abiogenesis in a lab, it might be the case that although abiogenesis is possible, we were still designed.

On the basis of this last point, I submit to you the idea that intelligent creation of life is a faith position where abiogenesis is not. There may be additional ways to establish this comparison, but I'll leave it at that for now.

I've seen the genetic code argument before, you know. The idea is that all codes are intelligently designed, so the existence of one in DNA proves a designer. That's an argument from ignorance because there is no evidence that a code is impossible without a designer. Further, if you present this argument, I can provide examples of naturally occurring codes which have nothing to do with life, like the means by which mineral crystals can transmit their structure to non-crystallised material.

There's another side to the genetic code argument which states that it's impossible for new information to appear naturally. We've been over that here.

Let's go through this very carefully.

- We have about 8,000 years of recorded human history. Humans are the only creatures who have ever deliberately recorded it. All time before that is referred to as PREhistory for a reason; the universe pre-dates recorded history. By about 15 billion years.

- The Big Bang was a sudden expansion of matter. It did not create any heat, because all heat was contained within it; it merely dispersed heat like it did matter. It did not necessarily create anything, since nothing stops the matter from having existed before the Bang. It did not destroy anything either, because there was probably nothing outside the Bang that it could destroy. Comparing the Big Bang to an explosive detonation is a gross oversimplification.

- Present-day black holes do contain vast amounts of matter compressed to a single point, or singularity. It happens when the gravity of an object is great enough to overcome the magnetic fields keeping the atoms apart. Current physics do allow for this.

- Even if time as we know it resulted from the Big Bang, it's not necessarily all the time there's ever been. What if another system of time and space existed, and the Big Bang spawned from this? Perhaps another universe?

An atheist doesn't know how the heck the Big Bang happened, because we haven't found enough evidence to make any theory remotely certain. I'm comfortable with that. If I adopted one hypothesis as the truth now, I'd have to fault every other theory out there without any support at all.

Finally, don't take offence but to assert beyond doubt that a God is responsible for something merely because of the absence of known alternatives is the very model of an argument from ignorance.

I won't cover abiogenesis (the origin of life) here, because neither has MrPeters.
