The final hypothesis is Panspermia, which argues life on Earth originated from deep-space meteoroids billions of years ago. M. J. Burchell (2004, p.73) discusses, in Panspermia Today, the concept of Panspermia. Panspermia describes the “natural migration of life through space,” as meteoroids thought to harbor amino acids impact planets. Scientists since the mid-twentieth century have been continuing to define what Panspermia is, the possible different methods of transferring life across space, and the mathematical probabilities of different transfer methods. The term “Panspermia” was coined by Swedish scientist Arrhenius, who hypothesized rocks could withstand temperatures higher than their surroundings. Nonetheless, heat-resistant rocks would

According to M. J. Burchell (2004, p.79), when it comes to answering where life originated from, Panspermia fails to produce a solid answer that is not based around speculation. Abiotic synthesis and the deep-sea vent hypothesis both agree some form of abiotic synthesis led to life arising in a primordial-Earth environment with a highly pressurized atmosphere. Panspermia does not evaluate the process of how amino acids on Earth came to be, but rather how they arrived on Earth inside a possible meteorite. Results from tests on the Murchison meteorite reveal there are similar amino acids found on the meteorite and the amino acids created in Stanley Miller’s experiment (Wolman et al., 2004, p.809). Meaning, both abiotic synthesis, the deep-sea vent hypothesis, and Panspermia, all rely on a similar process of producing life’s precursors, but abiotic synthesis is the process of how these organic compounds are created. A key difference between Panspermia and the other two hypotheses is Panspermia cannot be proven and relies on little evidence to support it’s argument. In comparison, there is much evidence to support abiotic synthesis and the compounds surrounding the LCHF and black smokers have been collected and analyzed, a flaw in Panspermia is evidence is dependent on future meteoroid
