I have been open minded to the possibility for a long time. Why not. But some of the programs that I have seen on T.V. in the last year or so has made me a little uneasy. On UFO files the one about the black box recordings is scary. Some of these sightings were so long ago that there could not have been anything here on earth to compare to what has been seen. Also the USO programs are compelling too. I think that they are out there. There has been more and more info released for public viewing. Are we getting close to an event?

I would say very likely, since there are billions of planets out there. Maybe we're the most advanced ones of all.

It is likely that life exists on other planets, at least in its simplest form, bacteria. What we do not know is whether intelligent life exists. It is unlikely humans will ever answer this for certain, it is one of nature's great mysteries. However, it is likely that there exists intelligent life somewhere out there. Think about it.... we live on one out of eight planets; in just one of over 170 billion galaxies. (A galaxy is typically about 1,900,000,000,000,000,000 miles in diameter, so multiply this by 170,000,000,000 and you'll have a good estimate of how big the universe is even not counting empty space [there are voids out there 19,000,000,000,000,000,000,000 miles big!] Compared to this, Earth is tiny, only about 7,917.5 miles in diameter!) Our 170 billion galaxies make up our massive observable universe. Our observable universe is only what we can see with present technology, who knows what small part of the whole universe this might be? If you consider the infinite vastness of space and planets, it is likely there is one planet out there that harbors living, breathing, thinking humans.

i dont think there is life on other planets. life on other planets cannot be proven only can be seen . since we are unable to see any life from other planets, there is no life on other planets. thats why our earth is so important. since only life existed on the earth in this univese, the earth is most important part of the universe. maybe earth is as important as total importance of other parts of the universe.
