Large asteroid impacts produced globally lethal conditions by evaporating large volumes of ocean water on the early Earth. The Earth may have been continuously habitable by ecosystems that did not depend on photosynthesis as early as 4.44 Gyr BP (before present). Only a brief interval after 3.8 Gyr exists between the time when obligate photosynthetic organisms could continuously evolve and the time when the palaeontological record indicates highly evolved photosynthetic ecosystems. 
Thinking of biology: asteroid impacts, microbes, and the cooling of the atmosphere.
TLDR
The authors examine the cooling of the Earth's surface from 3.75 to 1 billion years ago to propose the evolutionary sequence of microbes, which is proposed to be anaerobic heterotrophs, chemoautotophs, and then photoautotrophic microbes.

TLDR
It is shown that bolide impacts between about 3.6 and 4.0 billion years ago could have episodically melted an ice-covered early ocean and could have been important for the initiation of abiotic reactions that gave rise to the first living organisms.
Impact delivery and erosion of planetary oceans in the early inner Solar System
The terrestrial planets may have acquired oceans of water (and other surface volatiles) as a late-accreting veneer from impacts of comets and carbonaceous asteroids during the period of heavy
Geologic record of partial ocean evaporation triggered by giant asteroid impacts, 3.29–3.23 billion years ago
Although lunar studies suggest that large asteroid impact rates in the inner solar system declined to their present low levels at 3.8–3.7 Ga, recent studies in greenstone belts indicate that
Refugia from asteroid impacts on early Mars and the early Earth
Impacts of asteroids and comets posed a major hazard to the continuous existence of early life on Mars, as on Earth. The chief danger was presented by globally distributed ejecta, including transient
The Early Record of Life
Over the last 3.5 Gyr, the biosphere has had a profound influence on the atmosphere, hydrosphere, and lithosphere, at or near the Earth's surface. However, the conditions when life originated were
Ancient oceans, ice sheets and the hydrological cycle on Mars
A variety of anomalous geomorphological features on Mars can be explained by a conceptual scheme involving episodic ocean and ice-sheet formation. The formation of valley networks early in Mars'
3 Early Life on Earth and Analogies to Mars
The evidence for early life and its initial evolution on Earth is linked intimately with the geological evolution of the early Earth. The environment of the early Earth would be considered extreme by
Early planetary environments and the origin of life
TLDR
The Earth accreted from planetesimals 4.6 Ga1 ago and at least some of the precursor organic compounds were impact-delivered to the early Earth by comets, which supplied much of the Earth’s volatiles.
