Imagine that the year is 2045, and scientists have just discovered an extra-solar planet, roughly the same size as Earth, and its atmosphere contains all the signs of life, O2, O3, and CH4, and etc. But that's not all, the scientists are up to another shocking discovery, they have also detected the trace of a chemical called Chlorofluorocarbon, or CFC, a sign of the planet having an industrial pollution which is a sign of technology. As it happens, astronomers around the world, quickly swing their telescopes towards that planet in hopes of being the first one to capture an alien transmission. Then, a group of astronomers in the California's desert have finally detect an anomaly through the vacuum of space, they have finally detected the what might seem like an alien transmission from that planet. But that transmission does not make any sense to anybody. It's the same as we didn't know what the Egyptian hieroglyphics meant for a very long time until people have managed to decipher them. The same principle applies here. And even though as scientists won't be able to translate and decipher those alien signals, that would still be the greatest scientific discovery of all times, it would finally prove that we are not alone in the universe. But there's another problem, and that is, what to do next? If I would have to make a decision, I would keep those news quiet, instead of letting the entire world know about it. The thing is, who will be in charge for making decisions in that case? Should we transmit a signal back to them (it could be done by beaming up laser signal containing all of our information), but wouldn't doing so be an extremely foolish thing to do? What I mean is that, we have just discovered another intelligent life, and we have no experience in that field. That is to say, we would not not whether those extraterrestrials are friendly or not. And even though it is unlikely that those extraterrestrials would be able to get to us (it would normally take an estimated of a thousand years), it might be possible that those extraterrestrials have exited for much longer than we humans have, and so they might be able to travel at the speed of light and actually reach us in about twenty years. But there's another problem, if everybody would find out about that discovery, first of all, many will freak out, panic, while others will be extremely happy. Next, there will be freaks who will try to send or beam up unauthorized signals to that planet, and as the result of that, what would happen if twenty years later, our telescopes detect a fast moving object, who's shape is too smooth and accurate to be an asteroid, and that is heading directly towards Earth. As it comes closer, it is clear that that is an alien spaceship. As it approaches our planet's atmosphere, it splits into two and each settles into position above each pole. Panic spreads, as spaceships appear at equal distant points around the globe. So, are they here to crush us, or like us, are they driven by the quest for knowledge, to meet a new neighbor?
