I saw on some show in the national geographic channel, talking about finding another habital planet after the earth is used up, and they were saying that evenm just in our galaxy there are thousands of planets that probably have intelligent, just in the milky way....

This whole subject really gets you thinking man, it really blows your mind how small even our life spans are in the grand scheme of things, we liv 100 yrs at the most, but planets last billions of years, and there is no telling how long the entire universe has been around.... whoa
