One possible definition for the origin of life on Earth is the time at which the interval between devastating environmental insults by impact exceeded the timescale for establishing self-replicating proto-organisms. A quantitative relationship for the Hadean (pre-3,800 Myr ago) and Early Archean (3,800 to 3,400 Myr) impact flux can be derived from the lunar and terrestrial impact records. Also, the effects of impact-related processes on the various environments proposed for abiogenesis (the…

Impact constraints on the environment for chemical evolution and the continuity of life
TLDR
The frequency of giant terrestrial impacts able to stop prebiotic chemistry in the probable regions of chemical evolution is explored to suggest life probably could have originated near the surface between frequent surface sterilizing impacts.
The violent environment of the origin of life.
The Role of Meteorite Impacts in the Origin of Life
TLDR
It is proposed that meteorite impact events are a fundamental geobiological process in planetary evolution that played an important role in the origin of life on Earth and should be considered prime sites in the search for evidence of past life on Mars.
The Geology and Habitability of Terrestrial Planets: Fundamental Requirements for Life
Abstract The current approach to the study of the origin of life and to the search for life elsewhere is based on two assumptions. First, life is a purely physical phenomenon closely linked to…
Estimates of the maximum time required to originate life
TLDR
The impact model suggests that it is possible that life may have originated more than once and the maximum time required for the origination of life is the time that occurred between sterilizing impacts just before 3.8 Ga.
The early environment and its evolution on Mars: Implication for life
There is considerable evidence that the early climate of Mars was very different from the inhospitable conditions there today. This early climate was characterized by liquid water on the surface and…
Origins of life: A comparison of theories and application to Mars
TLDR
It is found that the entire range of current theories suggests that liquid water is the quintessential environmental criterion for both the origin and sustenance of life.
The seeding of life by comets.
Exobiology, the study of the origin, evolution and distribution of life within the context of cosmic evolution: a review.
Seeding life on the moons of the outer planets via lithopanspermia.
TLDR
It is expected that material from Earth and Mars to the moons of Jupiter and Saturn is most likely to occur during the Late Heavy Bombardment or during the ensuing 1-2 billion years, and there are significant rates of re-impact in the first million years after ejection.

Impact structures are the dominant landform on planets that have retained portions of their earliest crust. The present surface of the Earth, however, has comparatively few recognized impact…
Extraterrestrial Cause for the Cretaceous-Tertiary Extinction
TLDR
A hypothesis is suggested which accounts for the extinctions and the iridium observations, and the chemical composition of the boundary clay, which is thought to come from the stratospheric dust, is markedly different from that of clay mixed with the Cretaceous and Tertiary limestones, which are chemically similar to each other.
Ion microprobe identification of 4,100–4,200 Myr-old terrestrial zircons
