And that’s the idea behind panspermia. I’ve been asked many times why panspermia isn’t just another layer of turtles. People have commented that moving the creation of the basic building blocks of life from Earth to space just adds a step and doesn’t make their creation any easier to explain. Yet in fact, it does. We’ve detected the basic building blocks of RNA and DNA in space. Conditions are ideal. The raw materials are there, the energy is there, and the components can come together through simple Brownian motion without requiring a solvent.
