In a layer on Earth, insoluble organic material:

"thin layer of 3.3 billion-year-old rock contains unexpected treasure: organic matter that was carried to Earth by meteorites when the planet was still young.
The find supports the idea that organic, meaning carbon-based, chemicals from space supplied some of the raw materials for the first life on Earth. It could also complicate the search for life on other planets.

“'This is the very first time that we have found actual evidence for extraterrestrial carbon in terrestrial rocks,” says Frances Westall of the CNRS Centre"

"Electron paramagnetic resonance (EPR) analysis of carbonaceous, volcanic, tidal sediments from the 3.33 Ga-old Josefsdal Chert (Kromberg Formation, Barberton Greenstone Belt), documents the presence of two types of insoluble organic matter (IOM): (1) IOM similar to that previously found in Archean cherts from numerous other sedimentary rocks in the world and of purported biogenic origin; (2) anomalous IOM localized in a 2 mm-thick sedimentary horizon. Detailed analysis by continuous-wave-EPR and pulse-EPR reveals that IOM in this layer is similar to the insoluble component of the hydrogenated organic matter in carbonaceous chondrites, suggesting that this narrow sedimentary horizon has preserved organic matter of extraterrestrial origin. This conclusion is supported by the presence in this thin layer of another anomalous EPR signal at g = 3 attributed to Ni-Cr-Al ferrite spinel nanoparticles, which are known to form during atmospheric entry of cosmic objects. From this EPR analysis, it was deduced that the anomalous sedimentary layer originates fromdeposition, in a nearshore environment, of a cloud of tiny dust particles originating from a flux of micrometeorites falling through the oxygen-poor Archean atmosphere."

Comment: This article shows the Earth received organic material from space early on, but this stuff is insoluble, and even if the Earth is very water rich, how does that contribute to forming the proper proteins to start life? Still quite interesting
