We already knew we weren't on an average planet. We know of 9 planets, and ours is the only "good" one, thus in the 'known universe' of planets ours is very unaverage. However, you seemed to be trying to use that video as evidence that life should not exist naturally, and that is an error. At best, even if we accept for the moment that everything it says is true, it only provides evidence that we should be the only life in this galaxy. As I said before, if we include the entire universe and still say that the odds of life are 1x10^-15, life is still likely to happen somewhere. It just happened to happen here.
It's true in a sense, we only have found life on Earth at the moment.
******* Not a flame against Skruples, more likely a support of his theories *********
Both Mars and Venus are pretty much equal good as Earth to have life on it, being within the right distance from this type of star.
The problem is that Venus have a really bad case of Global Warming at the moment, it's too hot there for us.
And Mars is the opposite, not enough Greenhouse Effect to keep it warm enough for things like us to live there.
And then we have the problem with the composition of the atmosphere there, but then again, life that would grow and live there would probably be adapted to that environment.
Just look at harsh environments on earth, we have stuff living in superheated sulfer-laden water, and they will die if we move them to plain water.
It’s all about adaptation, or a God with a good sense of humor.
Or whatever you believe created and still mutates or maybe upgrades the different types of things that exist on earth.
The bottom line is that all three planets could have life on them if the conditions on the actual planets would be acceptable.
Keep in mind that Earth can be the next Venus if the Global Worming continues, a change of climate for a planet can go pretty quickly, and it’s more or less reversibly.
3 out of 9 is pretty good in my point of view, then again our solar system might be a really weird one compared to all the millions millions millions solar systems out there…..
