The point here is, the universe is just so big that our brain is not made to hear and process large numbers like this. We orbit around sun, one of the 500,000 Million stars from our galaxy. This image from Hubble telescopes shows that there are billion-times-trillion such galaxies in the universe. The number is so big that the probability of not having life in some other planet is almost zero. Watch this remarkable video to be amazed.
