I think that science is going to satisfactorily explain how life began in the very near future. Astrobiology will lead the way as we learn more about how chemical processes on exoplanets evolve. Applying this to Earth, we are going to have to wrestle with the question “what is life?” As simple chemical processes increase in complexity, biological processes emerge like self replication and metabolism. It is going to be difficult to draw a line between life and non-life as, my guess, it will be a long drawn out process in time with many branches. What we call life will be still be a common decent through natural selection process. And it was be a long, long process going from a sack of chemicals to a cell perhaps 100s of million of years. Betting that the RNA world will be found to be an important middle milestone in the creation of life on Earth.
