Our tiny speck was the tiny speck that mattered.

The use of the word “evolution” is carefully constrained in such remarks, to leave plausible deniability to a creator.

But that is like using weasel words to suggest that the historical line of Ford automobiles came into being without Ford.

Because, any being that would fit the definition of “God” exists independently of His own creation, and that creation includes time.

...

Then what is the definition of God? I ask, because if science is to be held to a high standard, then so should those who criticize it.

Oh yeah, the chance is the base. What mutations are successful are not chance. That’s my point but as you say, without the chance mutation you have nothing.

Biblical theology as we know it firmly asserts that this is impossible: “Who has been His counselor?”

Goodness can only be learned FROM God. We don’t even know everything that the Sun is (not even whether it flickers on a scale of millennia — a quite possible explanation of the appearance of historical climate changes).

It happened once that survived. However, it occurred awfully early in our history as a planet. Some interesting research will have to chase these questions.

Or some humility may have to confess that we might never know.

It's really rare in the Universe for a planet to have free atmospheric oxygen. It combines with other atoms so readily to form stable compounds, that most oxygen gets trapped permanently in surface rocks and so forth.

As I understand it, just about the only way to generate free atmospheric oxygen, is by photosynthesis. There has to be a whole lot of green plant activity over a long period of time, continually producing new O2 to replace what gets trapped in silicon oxides, iron oxides, you-name-it oxides on the earth's surface.

Detecting atmospheric O2 on some other planet would be a very strong marker for the presence of tons of plant life.

Or so I'm told.

Smart FReepers? Does this make sense?

Having a lot of carbon around gives you a reducing environment (consumes oxygen). The world definitely has both carbon and oxygen.

One thing I do know. Clever wordsmithing does not equal science. It may be rhetoric, it may be poetry, but it does not equal science. Science would care about everything, not just a narrow line of narrative.

And my favorite OEC’er, Hugh Ross, points out quite a few things about the situation of the earth that have made it hospitable to life (something which would have to happen before it could even be the tiniest bit plausible that it would be able to host any kind of “evolution”).

This little speck is quite a rare little speck, to all appearances. We do not have a plethora of worlds in this universe that look enough like this one to live on, Star Wars and fictional places like Tatooine with their herds of blue milk bovines notwithstanding.

I am not at all well-informed on atmospheric chemistry and physics. I hardly know enough to ask a good question.

It seems to me, though, that we have so *little* carbon in our atmosphere (CO2 is 400 ppm, which is only 0.04% --- compared to O2, which is 21% or thereabouts.) It's hard for me to see how that little carbon dioxide effectively keeps enough plant biomass alive to keep up our rather astounding oxygen levels.

Does that make sense?

Yes, photosynthesis is one of the wonders of this earth. And most of it isn’t even happening where it is obvious to the land dweller’s eye. Most of it’s happening in the oceans, those bodies of brine that not only don’t challenge what lives in them, they support it vibrantly.

(I wasn’t picking on you by the way. I was picking on the self-evolutionism ideas.)

That is inherent in the asking. Failure is always an option. Every hypothesis must be falsifiable. The humility to stop asking questions is likely beyond us, me anyhow.

One of the questions that needs to be asked is what do we even need to know before we can get to the place that we are purporting to be so curious about.

Jumping too far and too fast leads to fiascoes like global warmism.

Ah, no. They are incongruous, incompatible. False premise: “I believe that many religious people are uneasy with the concept of evolution because it makes them feel smaller and God more remote over vast gulfs of time.” Your belief has no historical or scientific justification or basis. This is not an issue that can be addressed in a few paragraphs.

Global warming needs more research, not less. Eugenics was the global warming of its era. It was proven to be bull by research not directed by political certainty.

We have good evidence now that the last common ancestor lived around a hydrothermal vent. That isn’t necessarily where abiogenesis occurred but still an amazing result. All of life on Earth goes back to that one small place at one point in time.

-——We are a tiny spec in the universe. I think it’s very unlikely that the son of God was born on the earth. Let’s not be so self-centered and arrogant!-——

You base that proposition on the idea that there is intelligent life somewhere else in the universe...

Statistically that is a huge number, not life itself, but intelligent life...

After all God said we are made in his image...

-——Evolution and a divine creator are not exclusive. I believe that many religious people are uneasy with the concept of evolution because it makes them feel smaller and God more remote over vast gulfs of time——

You have to define evolution....certainly micro evolution is evident...

Macro evolution is simply a hoax, there is not one speck of evidence despite decades of searching to find one species to species transformation...

In the beginning....God...
