What would surprise you more.. We are alone in the universe or there are thousands of sentient beings out there.

Carl Sagan championed the idea that there were thousands of worlds out there with intelligent beings. Others have said that its only us... on this nondescript planet in a nondescript solar system in a mediocre galaxy. I would feel more comfortable to know we are not alone.

    Jul 29 2013: Carl Sagan also observed that we humans have only been able to effectively communicate with other beings for a few hundred years which compared to the life of our planet 3.5 billion years is no time at all. If the same holds true for the aliens the biggest problem is not the distance between us but rather do our time frames match up. For example if the aliens were available (existed) 70 million years ago they would have only reached dinosaurs on earth.
