Dear history channel:

Did you read what I wrote? Its not about possibility, its about probability. We humans are on this earth for a few hundred thousand years, which in "galactic" proportions is not even a wink. Just for a few years we have been able to leave earth's orbit or send spaceships to a few planets within our galaxy. Contact of the third kind would require a) a far more advanced alien technology and b) it would be needed within this unbelievably small period of time we are even here. It's not impossible, it's just extremely unlikely. A scientist would not say, there's definitely no god (or alien contact in that matter), he would say its so unlikely, that it may as well be treated as not existent, until there is any proof. That is a huge difference, and sorry, but if you don't get this difference, you should probably not discuss science. In science, no such thing as an indisputable fact can exist. The lack of actual information cannot be taken as a proof, and that is what deGrasse Tyson said.

And your PhD is in what field again? You make my point for me in your response. We are newbies, but if there is a PROBABILITY that there are older civilizations out there, then there is a PROBABILITY that they are more advanced than us. Therefore there is a PROBABILITY that they began exploring the universe before us, leading to a POSSIBILITY that they COULD have contacted us. Less than a century ago there was an astonishingly widely accepted PROBABILITY that blacks, homosexuals, the mentally challenged, the infirm, many immigrants and others were of a lesser intelligence and should be controlled for the greater good. This have rise to eugenics, which was championed by a man named Hitler. Science rules.

Three (3) probabilities in a chain and you still don't get it. Whatever man. Still nobody denies the possibility. And this ending up your argument with Hitler is just epic. Oh, btw: my PhD is in bullshit detection.

Waste of a couple hundred thousand obviously.
