Toowoomba, water recycleing

[silkwood]

Silent: notice in your quote the author says "pretty much". That's what I meant by "for all intents and purposes all" because the amount of water produced by chemical reaction is infinitesimal in relation to the amount of water on Earth. Yes your car does produce water from complex chemical reactions, taking the componentry from the atmoshere and the fuel. It is not just "left over water" from the air used in combustion. Did the molecules in this water come from water at some point? Probably so, in fact almost certainly. Were all of these available molecules originally present on earth only from water? Highly unlikely that all of these molecules came here that way, regardless of your preferred origin theory (keeping in mind that's all they are). However the overwhelmingly vast majority of them would have, given water's abundance and its utilisation of most of the critical components available on Earth. Note no-one is saying the molecules are new and have been created (well actually a few scientists believe we are receiving molecular bombardment which ever so slightly outweighs the loss from our planet,but, well are the words "bees-dick" familiar ).

I think the question "is new water created from existing matter" has to be answered with a resounding YES. As to whether those molecules only ever originally existed as water- probably not, but overwhelming majority yes. It is probably fultile arguing about this particular point as you are on the money when you say the mass production (absorbtion/creation/impact) of water does not and will not happen now.

By the way, look up "punctuated equilibrium", Gould (and others) suggest evolution is not a smooth line, but possibly a series of abrupt changes interspersed with smooth-appearing changes. We will not see apes changing into humans not only because the process is way to long for us to observe but the same conditions will not occur again.

That's what I meant when I said "if it can be said to have a rate". It's like so many natural processes that occur constantly, in that they don't actually ever stop, but in fits and starts where nothing seems to happen for a long time and then they happen all at once, like a volcanic eruption or an earthquake which builds up over a long time and then manifests itself spectacularly.

I think we are more in agreement than disagreement. I'm still getting over being compared to a creationist arguing against evolution

Have you ever been to England and walked inside one of the old houses?

Yes, I have. But that doesn't mean that the people were necessarily shorter then; it could just mean that the doorways were expensive to build.

As a matter of fact, I don't recall ever hearing that water has EVER been discovered anywhere else.

No longer true silent. Just a few days ago there was an article that said that water had definitely been found on a distant planet outside this solar system.

Wouldn't that be like saying the holes in a doughnut cost more to make the larger they are?

Not that I doubt it, but I don't think that's conclusive yet. I must say it's beyond me how they can work that out. I suppose they're analysing the light waves or something to predict the molecular structure of the vapour they're looking at. Apparently another team had failed to find any sign of water a couple of months ago. Be interesting if it's true though.

Stop being a cycnic. They had a chat with the little green men

So does it taste like Earth water, Daddles?
