Where are all the aliens? | Stephen Webb
The universe is incredibly old, astoundingly vast and populated by trillions of planets — so where are all the aliens? Astronomer Stephen Webb has an explanation: we’re alone in the universe. In a mind-expanding talk, he spells out the remarkable barriers a planet would need to clear in order to host an extraterrestrial civilization — and makes a case for the beauty of our potential cosmic loneliness. “The silence of the universe is shouting, ‘We’re the creatures who got lucky,'” Webb says.

Galaxy and Universe population had to start somewhere and maybe we are that starting population. If so, in another few thousand years we should be spread across our galaxy. Maybe sooner if technology keeps advancing at the present rate.
I, too, am an expert on space aliens. I have met as many as he has.
The earliest known start date for a technical civilization is ours. We have no data to suggest otherwise.
He looks like Mik Kanrokitoff from Tintin Flight 714 to Sydney, the scientist who had connection with extraterrestrial beings.
We are the aliens. The real people are spirits.
how often do you find man-made things under the sand (lost items, mines, treasures, etc)? and there are far far far more planets in the universe than all the grains of sand on earth.
"I've discussed it with dozens of experts" You can stop there.
Least funny stand up I’ve ever seen
Over a trillion planets in our galaxy and we are the only living beings? Duh!!!!!!!!
Aliens are the devil
First 30 seconds of this video. When I was a kid I saw the same thing he described. Again as a teenager going on a midnight hike at colt creek state park in Florida.
God is your alien who gave you life and spirit, for you to reject in your greed. Now earth will cast you off.
Humans will likely kill themselves off before we know anything about life elsewhere.
