One of the big unsolved problems inn science is how ‘life’, or more precisely, the first self-replicating molecular, came into being. Popular theories suggest, among other things, that life originated in deep underground thermal vents.
Via Machines Like Us I came across this article that suggests another possibility of how life began on Earth and possibly other planets. It says it might have happened in hollow tubes of ice called ‘brinicles’ that grow downward in the oceans near the poles, creating what the authors call a ‘chemical garden’ that has the ingredients necessary for producing life.
The origin of life is often proposed to have occurred in a hot environment, like the one found in hydrothermal vents. It is proposed that chemical-garden processes are involved in the mechanism. But there is a different school of thought that presents sea ice as a promoter of the emergence of the first life. Brine rejection in sea ice produces all the conditions that are considered necessary for life to appear.
The origin of life is a difficult problem and one should not think this is the solution. It could well be wrong. But the point is that people who think that scientists have no clue as to how life could have originated and that therefore a god must have done it are quite wrong. People are exploring all manner of avenues.
