What we should really be asking is this - Is there any intelligent life in America ?

arizona meteor crater is 50,000 years old, not 5000.

The Fermi myth again. All Dr. Fermi did was make one offhand remark over lunch. He never wrote a thing on the subject, so it isn’t known what he actually thought about it. In particular, he did not make an argument that we are unique in being an advanced life form.

These people (who are proponents of SETI) always talk about the vastness of the universe, but most of the universe is vastly far away in both space and time. There is only one large spiral galaxy close enough to be seen with the unaided eye - M31 in Andromeda. It is about two and one-half million light years away. The rest are vastly farther away. There is no practical point to considering galaxies other than our own. It is not possible, and will never be possible, to detect intelligent signals from other galaxies. Whatever turns out to be true for the Milky Way galaxy is likely to hold for all similar galaxies. We know that the Milky Way has produced one civilization capable of understanding and controlling electromagnetic radiation. I will stipulate that every large spiral galaxy is likely to produce at least one such civilization at some time during its existence, but I won’t waste a second looking for it.

er...um...er..er...um..um..um..er...err...um...um...umm....um...umm....!!!!!! Other than the several er's and um's, not too bad a lecture overall

Cradle of "man", not cradle of "mind".

but its only a factor of 10, which is acceptable in astronomy terms

Bacterial life is as common as muck. Now find out how common muck is.

and the answer is? ..........

Mostly good but all over the place at the end.

The acretian disc model of star system formation was dicredited some years ago. Thanks to new space photography that reveals stars and their planets being formed quite rapidly in the electrical paths of Birkland Current "Pinch Points" within gaseous clouds such as the Magellanic Clouds.

Look all u want ur not going to find it anywhere but earth

In this video Silk just repeats mantra,: worthless. He's not done his research on the subject (I find surprising, liked some of his videos), very narrow view presented. Not worth watching/listening. Maybe he just tested with this video what passes... Although I don't know how old these are, posted recent years, also lost the ball in dark matter (check mr. butler's yearly reports on physics/astronomy - he's got new stuff). On this video subject isaac arthur fermi compendium etc

Self organizing property of matter (Lovelock, Guya etc.) resulting from 'fine tuning' of the parameter space runs deep into quantum fields/string and particles/atoms/molecules transforming inanimate conglomeration of matter and force fields into life and consciousness, after winning millions of lotteries over billions of years, in a row (each with one in a million/billion chance of winning), implies intelligent design and divine purpose.

eeeemm, eeeeemm, eeeeemmm

please don't ever let that guy speak again...

Geeez. the academic racket or mafia :-) They have it made, what a cartel......

Attenborough makes up this evolution garbage as he goes along. He should realise by now what's staring him in the face that nature has "intelligent design". And I don't mean that of a bunch of ignorant scientists. Just a few things that cannot be explained. Migrations in general but that of turtles in particular. Turtles locate ascension islands, where they lay their eggs, from 1500 miles away. There are fish which actually change their sex. Cicada in America swarm every 17years exactly. Coral spawn together at the same time every year around the full moon. There's a frog which freezes and comes back to life. Flamingos are virtually the only living things that live in high altitude at extreme temperatures. There's a fish which lays eggs on a leaf outside the water. A bush which catches fire at 32degrees. The biggest lie. Globe earth. The earth is flat so the tides are not due to the gravitational pull of the moon and the sun. The tides are central to reproduction, or sex as "sir" Attenborough likes to call it, and feeding as are the seasons. None of which are due to spinning or any other HELLiocentricity fictional garbage. God created the lot. For truth about this and other establishment lies see rob skiba, Edward Hendrie, texe marrs, Eustace mullins.
