Because it's not actually stats, it's science. There are X number of stars in the known universe that are ideal for life. Of those stars there are Y that have proper conditions that are ideal for life. Of those there are Z that have planets within an ideal range where life could flourish.

And, yes, I will gladly acquiesce that this is all predicated on our understanding of science as it stands right now being correct. You may well be correct; there may well be a ton of variables we may not have thought of and even more that we wouldn't even grasp the fundamental understanding of.

Its just all enjoyable chat really; no one knows, probably never will, (aliens etc), and until we develop ourselves as 4 dimensional beings, which we probably wont, that will remain the case.

Height, width, depth we easily grasp. We dont even have to try to understand. Time is beyond us though.

"Where have the years gone?" We cant grasp the concept.

"Time is dragging" Ditto.

"My Brother is 6ft 5" You instantly know he is tall, and can measure it instantly in your mind without even seeing him.

We are a bit thick, cosmic wise.

I just got a fantastic TV Thursday and have been acquiring some good movies that show it's range, booted up Interstellar. One of the central points there is that gravity is something that can move beyond time. I still have no idea what they are even talking about lol.

Statistically it's not just improbable, it's impossible. Basically the Fermi Paradox.

I don't know how we can rule something impossible with very little evidence to go on. Even the Fermi Paradox use assumptions such as Earth-like planets being older must mean they achieve levels of civilisation faster than the rate on our Earth etc.

I didnt understand a word that Stephen Hawking said! Different level of understanding to me as a mere mortal.

Mars.

Open it up, full screen it. Stare at it and try to wrap your ahead around the fact you're looking at another planet.

Another thing to think about is the rare earth hypothesis. As infinite as the universe is the events that led to life on this planet are so unfathomably complex, from the rather strange layout of our solar system, to the impact of Jupiter on our planet when it moved closer to the sun then retreated out to its current location, to the collision of the earth that broke a chunk off and led to a perfectly sized moon that’s gravitational affect made for perfect conditions for life on this planet

On top of that there’s been 5 extinction level events in the 500 odd million years since the Cambrian explosion. We went 4 billion years with life on earth till the Cambrian explosion and before that it was all basically just algae The last one wiped out the dinosaurs and the biggest of them wiped out 96% of marine life and 3/4 land animals. My bet is it’s existed, reached a great filter and never got to the point it became an interstellar civilisation, came and went.

Also I don’t know if anyone watched the video I posted from PBS but even with all of what I’ve mentioned above, even if they did exist we’ll probably never have the technology to reach them. There will probably be life that comes after us that will never know we were even here. I think we will reach a great filter at some point.

Think this calls for some high quality graffiti going down.
