that we learned about an experiment trying to replicate the conditions that produced life from chemical reactions.
The Miller–Urey experiment[1] (or Miller experiment)[2] was a chemical experiment that simulated the conditions thought at the time to be present on the early Earth, and tested the chemical origin of life. Specifically, the experiment tested Alexander Oparin's and J. B. S. Haldane's hypothesis that conditions on the primitive Earth favored chemical reactions that synthesized more complex organic compounds from simpler inorganic precursors. Considered to be the classic experiment investigating abiogenesis, it was conducted in 1952[3

We have to realize that we do not know all the conditions that came into play at that time on earth, so that Miller-Urey were able to create the building blocks of life, amino acids, is significant.
There have been further studies that have created other components of life since then. It really could be a matter of time and more specific information before some form of life can be recreated in a lab. But it doesn't matter to me whether it can be done or not. Just because we are unaware of one component in the atmosphere at the time does not mean that it is impossible for life to arise.
However, many of the important building blocks of life have indeed been created in a laboratory, including amino acids, self-replicating RNA molecules, and self-sealing and self-replicating lipid bubbles (ie, cell membranes) which are profound steps toward the goal of one day creating fully-synthetic life.
