Cosmologist: A Trillion Trillion Planets, Zero Alien Evidence

88% of astrobiologists surveyed say extraterrestrial life exists. Ask instead whether there is evidence for it and the honest answer is close to zero.
Multiply zero by a trillion trillion planets and you still get zero. Here is why the numbers argument fails.

Brian Keating is Chancellor's Distinguished Professor of Physics at UC San Diego and principal investigator of the Simons Observatory.

We cover: why the rapid emergence of life on Earth is not the evidence people think it is, what a winter in Antarctica reveals about the large numbers hypothesis, the Earth to Mars meteorite exchange nobody has falsified, why the first fossils found on Mars may turn out to be terrestrial, and what phosphine on Venus actually established.

Suggestive data is not probative data. Those are different words for a reason.

00:00 No evidence yet. Only suggestive data
00:22 88% of astrobiologists believe. So what
00:59 A trillion trillion planets proves nothing
02:35 Why Antarctica kills the numbers argument
03:37 The falsification nobody has handed me
04:24 The fossils on Mars may turn out to be ours
05:26 Zero times ten to the 24th is still zero
