Ok, so theres about 100,000,000,000 stars in the average galaxy and about 100,000,000,000 galaxies in the known universe. This is a total of about 10,000,000,000,000,000,000,000 stars in the universe. Let's say that there's intelliegent life in one out of every hundred billion stars... shit, at those odds I'll probably get hit by lightning while recovering from my shark attack at the pool first!

With those odds, that means theres still another HUNDRED BILLION planets out there with intelligent life.

Do you seriously think humans 2,000 years ago had any idea what they were talking about? Haha...
