@ThatGuyWilliam9@SimonReye@RickyTheGuido You got it backwards, most people in the Levant looked more like that before the 7th century conquest from the Arabian Peninsula.
@DirkBruere@Gorilla91267617@skdh No there are many more.
1. Space travel is too difficult. We don't hear anything due to the inverse square law.
2. They are here, UFOs reported by astronauts, people, and the military have seen them thus there is no paradox.
@DirkBruere@Gorilla91267617@skdh Only really unique point about our planet is our large moon, which does stabilize the planet's tilt, but this process takes 40 thousand years and as we have seen with ice ages, plate movements and drastic changes in our own climate life can easily adapt.
@DirkBruere@Gorilla91267617@skdh Next plate tectonics, you need liquid water, and radioactive decay to allow for convection. Water, metals, radioactive material is abundant in second generation stars especially in the galatic core where our solar system formed.
@Gorilla91267617@DirkBruere@skdh It is not dumb nor is it obnoxious. Life DID change the atmosphere, and life was shaping the atmosphere for 4.5 billion years before humans even existed. Nothing about the Earth is unique, life formed immediately, transformed the planet which could happen anywhere.
@Gorilla91267617@DirkBruere@skdh Earth's atmosphere and composition has changed drastically. Before life the atmosphere was 85% water vapor, 12% CO2, 1-3% Nitrogen with pressure around 100-500 bar. And it was changed by life overtime.
Life on Earth changes the atmosphere.
@Gorilla91267617@DirkBruere@skdh c) An oversized moon
This is the only point that is unique, but life on Earth evolved around the conditions of our planet, a less stable tilt would be something life on other planets would have evolved to adapt to.
@Gorilla91267617@DirkBruere@skdh h) something to suck up asteroids (like our big planets)
Jupiter not only does not protect Earth as it redirects as many comets as it absorbs, but it's also the reason the asteroid belt exists which is what whipped out the Dinosaurs. So it actually makes it worse.
@Gorilla91267617@DirkBruere@skdh g) a friendly galactic position
The sun and Earth formed in the galatic center and moved out it's current position over 4.5 billion years. So by that standard there should be no life on Earth.
@Gorilla91267617@DirkBruere@skdh d) planetary tilt
This is common and not unique to Earth.
e) an iron core- to create a magnetosphere
Not something that is rare, but you also need convection from plate tectonics which you would have with liquid oceans and radioactive decay.
@Gorilla91267617@DirkBruere@skdh But how can you believe Earth is so rare? I see nothing that makes our planet particularly rare out of the billions of sun like stars. I want to know what the parameters are.
@Gorilla91267617@DirkBruere@skdh Ok got it, so it is not just a rocket planet around a Sun like star that comprise of around 20 billion stars in our galaxy. Then what else makes Earth special?
