The universe can be examined with the assumption that humans are uniquely rational on Earth. Our solar system has three bodies with the potential for life: Earth, Mars, and Europa. Conservatively, every solar system has one body with life potential and 1% of those actually sustain life. There are more than 500 solar systems in the Milky Way Galaxy. In the universe, there are roughly 100 billion galaxies, which means 5x1013 solar systems. Therefore, there are 5x1011 bodies with life in the universe.

This means there are 50 thousand bodies with rational life in the
