"Panspermia is the hypothesis that life exists throughout the Universe, distributed by space dust, meteoroids, asteroids, comets, planetoids, and also by spacecraft carrying unintended contamination by microorganisms. Distribution may have occurred between galaxies, and not to have been restricted to the limited scale of solar systems."



From: https://en.wikipedia.org/wiki/Panspermia

Although, bacteria are also very tough. Tough enough to survive indefinitely in a space environment. They have the drawback of being uni-cellular. The thought of extravagantly multi-cellular creatures evolving from bacterium even in the geologic time span of the Earth is too much for me.

Tardigrades are multi-cellular creatures who include specialized cells such as light sensitive sensory organs. Plus, as the video explains, they could survive indefinitely in space.
