Alright, here's how it's going to go down in this thread. You're going to post your definition of evolution, the big bang, the biblical global flood, and abiogenesis.

I don't want anyone cheating and looking it up on "the google", now either. I want your working definitions and those alone.

I think it'll foster mutual understanding if we know what the other side of the argument is thinking when they mention a concept.

So, have at!

All right, I'll go first.

Biological evolution is the process whereby species acquire and lose characteristic features, becoming, in the process, new species.

The Big Bang
The original cosmic event, in which everything that exists came into being, along with the set of constraints (the laws of physics) that determined its subsequent evolution. It is not only plants and animals that evolve, as you know.

The Biblical Global Flood
An environmental catastrophe story in the book of Genesis, in which it rains for 960 hours, submerging the entire planetary landmass under roughly five and a half miles of water. When it stops raining, the waters quickly subside by about two and a quarter miles and a single shipload of survivors makes landfall. All other land-based animal life has vanished (drowned and squashed flat under the weight of all that water), but the group of survivors contains breeding pairs of every animal species previously extant, from which the planet is subsequently repopulated.

'Life arising from non-life' is the most succint definition I can think of. It is not generally used to describe divine creation, though the God of Middle Eastern monotheism shows few signs of being a biological entity in his creative phase; all that comes later for Christians, and does not come at all for Jews, Muslims and Zoroastrians. Still, abiogenesis is generally used to describe a stochastic process in which a Creator plays no part.

It is a conceptual hurdle for many, who doubt that life could have arisen from non-life without the intervention of consciousness. The vision of living organisms suddenly springing into being where before there had been only lifeless chemicals strikes them as improbable. And they are right. Abiogenesis would have been a long-drawn-out process in which chemical replicators of ever greater accuracy and complexity slowly came to display, one by one, the group of traits and tropisms we speak of as 'life'.

Consider a virus: it's just a twist of nucleic acid wrapped inside a protein molecule. It has some of the characteristics of life but not all; it cannot reproduce, for instance, but must rely on an external device -- the ribosome of its host cell -- to run off copies of itself. I don't believe viruses are regarded as transitional between early chemical replicators and life, but we can regard them as an analogue of what those transitional forms looked like.

Scientific materialist here, obviously.

Ooh! A pop quiz! I didn't study. Well, here you go:

Evolution: A proposed biological process that is supposed to cause natural selection via random mutations. The mutations helpful to reproduction are more likely to pass on.

The big bang: The beginning of the universe, followed by a rapid expansion of matter. Most (not all) scientists agree on this, as opposed to a constantly-existing universe without a beginning.

The Biblical global flood: An account presented in Genesis of a flood, the survivors of which were Noah, his wife, his three sons, their wives, seven of some types of animal, and two of others.

Abiogenesis: The idea of life spontaneously coming from non-living molecules.

I didn't read the other post yet, I'll compare our answers after posting this.
