Dennis, Jeff and Susan discuss the probability that there is Life, beyond Earth, in the Universe. Just think how long our universe has existed. It started with the Big Bang about 14 billion years ago. Now compare that number to how young human beings are on our planet, the Earth. How smart were we 2,000 years ago? Or 6,000 years before Christ (B.C.)?
Astronomer Bob Berman confirmed that our Milky Way Galaxy contains 400 billion stars, including our own star, the Sun. NASA is now able to detect other planets, like this planet Earth, revolving around those other stars.
Furthermore, our Milky Way Galaxy is one of a hundred billion galaxies. The laws of probability suggest there is Life, beyond Earth, in the Universe.
