Spontaneous Aristotle vs. Redi+Pasteur+Needham+Spallanzinonliving matter,
AristotleAristotle explains that life arose from non-living materials because it contained "vital heat".
Francesco Redi - Spontaneous generationFrancesco Redi designed a scientific experiment to test the spontaneous creation of maggots. This was considered one of the first experiments that proved the theory wrong.
John Needham - spontaneous generationJohn Needham performed an experiment that showed evidence for the concept of spontaneous generation in which he boiled broth infused with plant or animal matter, he argued that the new microbes must have arisen spontaneously.
Spallanzani - spontaneous generationIn Lazzaro Spallanzani's Experiment, he proved microorganisms could be killed by boiling.
Pasteur - spontaneous generationLouis Pasteur found that the broth did not have bacteria growth, thus proving that there was in fact nothing in the air that caused spontaneous generation, disproving the theory.
Interstellar or Litho - Panspermiaorganisms,
Interplanetary or ballistic - panspermiaplanets,
Hermann Richter - PanspermiaHermann Richter put forward the idea that life has always existed in the universe. In this theory, life has existed and will exist for all eternity, and so there is no need for an explanation of its origin.
Biochemical or molecular - Oparin 1923 + Haldane 1928organic,
Oparin-HaldaneThe Oparin-Haldane hypothesis suggests that life arose gradually from inorganic molecules, with “building blocks” like amino acids forming first and then combining to make complex polymers.

Miller - Urey 1953Miller and Urey combined warm water with water vapour, methane, ammonia and molecular hydrogen. Thus experiment successfully produced molecules from inorganic components thought to have been present on the prebiotic earth
Francis CrickHe said that RNA must have been the first genetic molecule, also suggesting that RNA, besides acting as a template, might also act as an enzyme and, in so doing, catalyze its own self-replication.

Nick Lane“There are multiple competing theories as to where and how life started. Underwater hydrothermal vents are among most promising locations for life’s beginnings – our findings now add weight to that theory with solid experimental evidence,”

Graham Cairns-SmithGraham Cairns-Smith formulated the theory of clay in 1985 in which life originated in a solid substrate, based on the ability of clay crystals to grow and replicate.

Whitehead institute for biomedical researchWhitehead Institute has used the method of making trillions of RNA go through test-tube evolution to collect evidence in favor of the RNA world view.
