Exactly.. How did the first DNA sequence form ALIVE?..
Since DNA can also be dead?.. Dead DNA is just protoplasm..
Even, Dead DNA would be almost impossible to form statistically..
Wonder why nobody cares what makes DNA ALIVE or NOT..
DNA is only wondrous because its alive, dead DNA is merely "SNOT"...
Who says it is "dead" - perhaps "dormant" is a better term since it mey be merely (temporarily ??) lacking the 'tools' to 'live.' After all, we can transpose genes from one organism to another. It is not out of the realm of possiblility, were we to find a complete strand of dinosaur DNA that we might bring dinosaurs back to life ... ???
As to the first part of how the first formed "alive" - that is the mystery, perhaps miracle if you wish, although I think it is just the possibility that there can be such a thing as DNA the underlying miracle.
