Bacteria Can Survive in Space

There's no evidence for it, but i don't think there's any reason why it couldn't happen. Bacteria can be entombed in grains of salt for a billion years. There are bits of mars that were blasted off the surface of mars that now are on the earth. The meteorite that brought the end of the dinosaurs had been a hundred million years in the making. It originated from a particular collision in the outer solar system and mas been circling around, waiting to strike.
