We keep finding the raw material of DNA in asteroids—what's it telling us?

Another asteroid yields nucleobases—the building blocks of DNA—reinforcing the idea that life's raw materials may be common across the galaxy. Analysis of sample returned by the Hayabusa2 mission from Ryugu found uracil, cytosine, and thymine at concentrations 32% higher than in previous meteorite samples. This isn't proof of aliens, but it suggests that prebiotic chemistry occurs wherever water and carbonaceous chondrites collide.
