We're a minority here..in earth conditions. Our existence has never been and is still not guaranteed. The mechanism in your example....the requirement -you- placed, would be earthlike conditions, wouldn't it? How is the "idea of limbness" independent of a mechanism, in that example?It's not independent of "a" mechanism. It's independent of "its" mechanism, in the sense that the idea will be represented, but not necessarily by DNA (or a CD or whatever). However, my idea is that given similar enough environmental conditions, the statistical chance of similar (or identical) ideas developing would be very high.
What I'm not sure about is whether DNA might be so overwhelmingly likely given Earthlike conditions that we might find something much like it in any water-covered planet with similar chemistry which has life.
It happens right here on earth, in independent lines of evolution, whenever similar demands are placed on organisms. It's called convergent evolution. It's fairly reasonable to presume that, given enough time and earth-like conditions, we could expect to see things like eyes, limbs, swimming plan-forms (e.g. sharks and dolphins), digestive tracts, respiratory systems, and neural clusters near the sensor-end developing, as we see on earth. Whether that's driven by DNA or some other chemical is entirely a different question.
The life will probably not closely resemble that which we have one earth, except in such cursory basics (Three- or four-eyed creatures? Trilateral or radial symmetry? Who knows?), but I agree it's safe to predict that similar circumstances would be likely to produce similar-ish creatures.

I replied: Can I refuse? Because I find the entire concept of vicarious blood sacrifice atonement to be morally abhorrent, the concept of holding flawed creatures permanently accountable for social misbehaviors and thought crimes to be morally abhorrent, and the concept of calling something "free" when it comes with the strings of subjugation and obedience perhaps the most morally abhorrent of all... and that's without even going into the history of justifying genocide, slavery, rape, misogyny, religious intolerance, and suppression of free speech which has been attributed by your own scriptures to your deity. I want a refund. I would burn happily rather than serve the monster you profess to love.
