That is false. There have been quite a few such experiments with positive results. The most well-known experiment related to abiogenesis is the Miller-Urey experiment which demonstrated the possibility of creating organic molecules like amino acids, the building blocks of life, from inorganic compounds under conditions simulating early Earth's atmosphere, using a mixture of gases like methane, ammonia, hydrogen, and water vapor with electrical discharges to mimic lightning strikes.
The Miler-Urey experiment has been replicated dozens of times and the results are consistent
