Microbes found in some of Earth’s oldest known uncontaminated water

Scientists used to think that the hot and dark underground environment would be inhospitable to life:

Researchers have uncovered the first direct evidence of resident microbes in Kidd Creek Mine, a 3-kilometer-deep copper and zinc mine in Ontario. The findings, published last month (July 18) in Geomicrobiology Journal, confirm previous work indicating that ancient, sulfate-rich water in the region could support what researchers call “deep microbial life,” and add to growing evidence that there’s a vast biosphere thriving in the Earth’s crust that has little or no interaction with the surface.

“This paper is groundbreaking, so to speak,” says John Spear, a microbial ecologist at the Colorado School of Mines who was not involved in the work. “They were able to get an idea of the amount of native microbial biomass . . . and they were able to confirm that the waters that the microbes are living in are host waters—they’re not contaminated or impacted by water coming from the surface.”

How they got there is apt to be a cause of speculation.

aligns with the YeC Moshe Emes, SPIRAL 'Draw Play' Lunar Formation hypothesis where day 3 vegetation and these microbes created, then the mass that is the moon drawn out from the Earth, resulting in the original single continent, and allowing these microbes to get to where they are.. so 5779-3 days = 5779 YA. so can date from 300M to 4.x B consensus YA the other option is during the 1656 Mabul impacts year 4123 YA that can consensus date from 25M to 300M +/- Pearlman
