Lecture 3 - Anybody out there?

This morning, I came across this video on YouTube. At first glance, it appears to be a very convincing piece of alien evidence. However, I'm certain that rather than a leaked government tape, it is most likely a leaked Hollywood tape, promoting an upcoming movie.

All that aside, what came to my mind was the thought of actual alien beings coming to visit us, and really how ludicrous this idea really is. Now, before anyone gets upset at me, let me say that I do believe that we are not the only intelligent life in the universe. It is simply too vast for us to be completely alone. I have no proof. Just a feeling. And as far as alien visitation goes, I also have no proof. Just a feeling. Oh... and logic.

Now, if we consider the age of the universe, and also buy into the idea that it all started from a single point, or a "big bang", then wouldn't that mean that all elements of the universe (stars, planets, etc.) are all the same age? And if that's true, then wouldn't all life have to be of at least the relative same age? Could another planet have cooled, been covered by water, plant and animal life, and had an intelligent species with opposable thumbs rise up to dominance? And could that species create craft that can travel through space for thousands (or millions) of years, at the speed of light, with enough provisions (or the means to create them) to sustain themselves and make that trans-galactic (or universal) flight?

They way I see it, if there is another intelligent species out there, similar to us, they wouldn't be any more advanced than we are right now. Is it impossible? No. Of course not. But it isn't probable, either.

The thought that aliens came to visit us in the past, teaching the ancient peoples of the planet to built pyramids, raise abundant crops, exploit planetary resources, and advance themselves into great prosperity, is a romantic thought, indeed. It just didn't happen. Think about the odds of another life form having the ability to find us, among the 10 sextillion (10,000,000,000,000,000,000,000) or so stars in the universe. Evading all the black holes, super novas, asteroid fields, comets, and countless other obstacles just to get here. And if they happened to find and use a "wormhole", how exactly did they know where it would go?

If you really do the math, and (for the sake of argument) say there are a billion other planets out there with intelligent life like us, that would still give one civilization a 1 in 10,000,000,000 (10 billion) chance of finding our sun, or any other star; let alone our planet.

It just didn't happen folks. But I'm not here to spoil your fun. I enjoy alien movies and science fiction stories as much as the next person, if not more. But I don't forget the "fiction" part of that.

We are not alone. But we certainly don't have to worry about our nearest galactic neighbors coming to borrow a cup of sugar any time soon.
