of life. According to Doug Hudgins of Ames Research Center, PANHs carry information for DNA and RNA and are an important component of hemoglobin, the molecule that transports oxygen through the body. They also make chlorophyll, the main molecule responsible for photosynthesis in plants. PANHs are formed in the winds of dying stars and spread all over interstellar space. "This stuff contains the building blocks of life, and now we can say they're abundant in space," Hudgins said. "And wherever there's a planet out there, we know that these things are going to be raining down on it. It did here and it does elsewhere." (Science Tuesday Oct 2005, 'Life's Building Blocks Abundant In Space' by Bjorn Carey).

Considering the trillions of planets in our own galaxy, the hundreds of billions of galaxies in the universe and how rugged, diverse and adaptive life is, there is virtually no scientific or logical probability that we are alone. In fact, there could be civilizations out there millions or even billions of years ahead of us! Is it possible that Earth has been, and continues to be, visited by extraterrestrial beings? The answer to this question is; of course it's possible, because there is no way to prove otherwise! We don't know who is really out there or what their capabilities are and that is an indisputable fact! Anything is possible! It's not crazy to be open minded about such things, what is crazy is proclaiming something doesn't exist without having even the slightest thread of evidence to back it up. It's time for us to stop pretending we are the be-all, end-all "masters of the universe" and accept the possibility that we are not alone. For many people seeing is believing, but until we have open contact, there's nothing wrong with keeping an open mind.

Keep your eyes open to the skies!
