We are only able to generate amino acids...this is all...amino acids are the building blocks or life. Its like someone saying that if you can prove that the ink in a textbook arises naturally it proves a naturalistic cause. When in reality its not the ink in the textbook thats important, the arrangement of the ink causing words. Or like someone saying the material a building is made of arises naturally, therefore the arrangement causing the building structure also arises naturally. You're using a flawed logic. However, if you proved that the building structure arises through a naturalistic cause, then that would be evidence for a naturalistic cause...Panspermia has gained ground for a number of reasons, but not at the expense of a naturalistic cause for life. Even if Earth's life came from somewhere else, life still had to start somewhere.
We are able to create light-reactive, growing, reproducing spheres in the lab. we are able to create organic compounds from inorganic compounds in the lab. Not full cells, certainly, and not anything complicated enough to call life, no. But the building blocks are in place, so I don't see the leap from where we are to a full man-made cell to be anything more than a gulf in time and effort.
If/once man creates a cell, however, people who believe in creation will certainly just start arguing that since man could create, then clearly God did too. It's not a reasoned position, and does not include a falsafiable threshold where the idea would no longer apply to a different, incompatable dataset.
It is not, in that manner, ever "wrong", as it's correctness cannot be tested (by design), however, neither is it ever "useful".
Again, people have been trying to create cells since the 1950s with NO success to show a naturalistic cause. Since no naturalistic explanation is available, this would show that an intelligent cause is inevitable, and also makes panspermia a more viable option. Take for instance if you found the Great Pyramids, but there was no historical evidence that humans built it, would you assume that it was intelligently designed or a natural formation, like a mountain? The material the Great Pyramids are made of arise naturally, with no need for an intelligent cause. But no naturalistic explanations for the design of the Great Pyramids have been found? What would you conclude?
