You are confused. We have not created life in the laboratory. What you think is life in not life.FALSE
Goddammit, you stupid fucktards keep repeating that LIE.
It's been done in the laboratory from scratch FORTY times already.
There are already three brand new species because of it, that never existed before.
Stop with the bullshit, 'kay? It gives righties a bad name.
Please refer to my other thread. You can see graphically how it works in real life.
We now have AI and neural network models for these things. In the brain, pushing a neural network into criticality gives it 50x the speed and 2000x times the memory.
In a segment of DNA, one change in a base pair (a "point mutation") can push the entire system into criticality.
I mean no offense, but you need to hit the books. This is not your father's science. Criticality is extremely complex, so much so we can't even tell what we're looking at most of the time. However we can pick up fractal and power law signatures that give us clues.
Science is TODAY, not yesterday. Yesterday, Craig Vetter and his colleagues created a minimal life form from scratch in the laboratory. They synthesized all the DNA by hand (or rather, by machine). There were ZERO components from existing living cells. This science has been replicated hundreds of times already, all over the world.
Today, biophysicist like me are revisiting micelles. We have now catalogued all the different ways proteins can embed themselves into cell membranes, naturally forming trimers and tetramers by adopting their lowest stable energies. All this occurs through SELF assembly, humans just put the right number of molecules into a beaker and the rest happens by itself.
Life is a natural and inevitable consequence of the fabric of spacetime. There's nothing magical or mysterious about it.
We have put together the components of what we think are the right things for life but it is still Chemistry and not Biology.
Even if we do ever produce life in a sanitized high tech laboratory that doesn't explain how those same conditions could have been reproduced in a primitive and possible hostile environment on the surface of a planet.
The only thing we will know if we ever do produce life in a lab is what we already know. That it is possible to turn Chemistry into Biology. We already know it because it happen here on earth in some very unique circumstances that may or not have ever been reproduced elsewhere. A step forward but not conclusive evidence that life exist elsewhere.
The much more conclusive evidence would be a little green man landing in a space ship or more realistic going to Mars and finding indisputable evidence that microbial life once existed before the solar winds destroyed the environment.

Synthesizing Life in the Laboratory: Why is it not Happening?
Laboratory abiogenesis is one of the ultimate goals of experimental biology. The most formidable barrier to create living matter in the laboratory is not the complexity of the cell, rather the absolute requirement for non-equilibrium steady state for all chemical reactions. Current synthetic...

At this point, the dead cell contains most of its nucleic acids, proteins, lipids, polysaccharides and metabolites. Therefore, while the genetic material, RNA, enzymes, polysaccharides and lipids are all necessary components of a live cell; their mere presence is not sufficient for life. In live cells, superimposed on all of the necessary biopolymers is the steady state non-equilibrium dynamics of all chemical events.

Has life been created in the laboratory?
No life has been created, there is no artificial life. There is only an artificial DNA, which can function as a natural one.

In short, no life has been created, there is no artificial life, there are no artificial cells. There is only (and it is a lot) an artificial DNA, which can function as a natural one, at least up to a limited number of generations. What remains until a living cell is artificially produced is still a colossal challenge, one that may never be overcome. And, of course, there is no point in trying to make pseudo-metaphysical somersaults from these experiments.
