What is your take on evolution/old age earth?

Smidlee, the comparison doesn't work. They are talking about highly conserved and identical sequences of RNA. The reason why they say they're primordial is because they are quite literally identical in all walks of life.

When you look at ATP Synthases, the DNA and amino acid sequences vary wildly and the mechanisms of action vary wildly from organism to organism. Unsuprisingly, the more complex the life form (and hence a larger energy output required), the more complex the ATP Synthase enzyme. In fact, it is just further evidence of evolution in action, as they have similar functions but have evolved to meet the energy needs of the host organism.

This is where we differ, of course ATP Synthases has to meet the special  needs of different life form yet there are similarities as well. (just like a lawn mower engine has similiarities with a F1 car engine)  This is not "evolution" in action, this is a statement of faith. (Both similarities and differences are so call evidence of evolution.) Thus "evolution" is just a label to slap on anything scientist learn about life. 

As far as blind faith , even scientist can be decieved  just any man can. (some clearly believe in some kind of god-subsitute) All throughout history it's been about nature gods (creators) vs spiritual ones.

 P.S Note the article state these RNA appears ALMOST everywhere in the tree of life (some have stated in the past this so called tree only exist in the human mind... just like RNA world) thus there must be  exceptions.

 This reasoning goes like  this:  Since it near impossible for these RNA appear once by chance then it''s even more impossible to pop up twice thus common RNA has to mean common ancestory.

This is going to be my last post in this as we will obviously have to agree to disagree.

Firstly, evolution has been observed in bacterial cells "in action", and continues to be observed in an on-going experiment. The evidence keeps growing and will continue to grow. You can come to different conclusions with the ATP Synthases but it's only a small piece in an ever-growing jigsaw of evidence.

Secondly, there are always exceptions and is hardly suprising given the length of time that has passed. And the tree of life is simply an easy representation and model to help humans visualise the complexity of life and different organisms.

Finally, your reasoning would carry some weight if RNA really was that difficult create. If scientists can recreate Earth-like conditions and observe the creations of RNA oligomers in such a short space of time, it really isn't a shock that RNA can be created over millions of years, likely occuring multiple times.
