> Your video I've just reviewed. Lots of acurate organic chemistry and lots of wishful thinking.
Or an incrediple perceptive imagination
>The current RNA studies on RNAzymes have reached the correct replication rates of about 99+%, not accurate enough for life, but an improvement over the first 95% models, after searching thru trillions of possible molecules.

> So far, I have not seen that efforts to define life have contributed at all to that understanding." http://www.jbsdonline.com. 
Here I agree with you ... life is like pornography ... I know it when I see it ... to quote a Judge whose name escapes me.
> Basically at 4 billion years lava, rocks and some water. Some organic material arrived by meteorite. How did the video author know that organic material was plentiful?
How do we know it was insufficient. Organic compounds can be made abiotically, this has been known for over a hundred years.
> Meteorite analysis, Murchison for example, have shown only eight essential amino acids, not 20. 
Who suggests all early life had all 20 amino acids?
> All living amino acids are left handed. Meteorite amino acids are 53% left and 47% right in a study last year. 
I would suggest a small difference in the availability of the early enantiomer would provide early life a sufficient drive to out replicate right handed enantiomer producers.-> All Ribose molecules in life are right handed, facts the video did no discuss. 
So what? That life can produce a specific handedness today is irrelevant. We are trying to work out what might have happened over 3.5 Gy ago.-> In conclusion, don't accept videos with beautiful symphonic and operatic musical background without deeply researching the subject yourself. OOL is a vital piece of the evidence in discussing agnoticism or theism. And it still looks miraculous to Paul Davies, who is now is sounding more and more like a diest.
If you reread my question i was not asking you to accept it?
 
> And finally from the video, how does information appear out of nowhere? A code suddenly invents its own information? Poppycock!
Information came when mankind created the concept.-Remember there is more information in a random set of events than there is a repeating set of events. It just harder to work out the key for the random set.-Poppycock indeed.
