>>7806029 One theory is that there are multiple universes and you are only conscious and aware and 'alive' is because you are in the one universe where it's possible to be alive.
So in most other universes, we all got killed a million times over during the cold war. So reality seems more bizzare as it goes along 'I can't believe we actually survived all that historical shit!' it's because if we had not, you would not be conscious to observe it, so since you can only observe a reality where human life persisted, the world/ timeline/ history gets more and more unbelievable and amazing.
Also, Fermi Paradox. Maybe humans are the only intelligent life weird enough to obsess about conquering the galaxy, other aliens are content living a carbon-neutral, biosphere-friendly life on a sustainable planet, forever and don't even listen to the radio because they love their kids too much to even care?
What's interesting is the way chemistry and physical states change dependent upon pressure and temperature. There might be some large exoplanets with rudimentary life forms underground where ionizing space radiation can't dissociate their molecule bonds, and flourish in a warmer, semi-aqueous environment. I'd think other than rainbow-wafer brain androids, that life could be semi-organic under certain conditions.
Also, I hardly think much of my own senses being part of the underlying nature of reality. The mind already imparts plenty in relating it's experience as something objectively occurring *cough cough time*.
>>7806029 Planets are fine tuned for life, the vacuum of space will kill any living thing that tries to survive in it. You not realize all the radiation that our ozone layer and magnetic field protect us from, had we lacked those this planet would be a barren craphole like Mars only bigger and cooler.
>>7806215 >Planets are fine tuned for life Incorrect. Life is fine tuned for the planets it exists on.
>the vacuum of space will kill any living thing that tries to survive in it Incorrect. Pic related.
>You not realize all the radiation that our ozone layer and magnetic field protect us from Only everyone realizes this. It's a little more complicated than that, but having a planetary magnetic field isn't uncommon or even rare.
>>7806029 >Why is the universe so fined tune for life?
"Life uh, finds a way" isn't too far off from the answer. The Universal law that energy can neither be destroyed nor created, only converted, relates to life. Life is just a result, given certain conditions, of energy conversion. Remove "life" from the universe, and your still left with massive amounts of energy being converted. It could be that life is an inevitable consequence of energy conversions seeking ever increasing efficiency. So a planet that receives x amount of energy from it's surroundings will evolve in to the most efficient form to utilize the most of that energy. Life would be part of the ever increasing efficiency, with sentient life capable of recovering/converting even more energy without disrupting planet cycles, being the ultimate in evolution from a energy conversion stand point.
tldr: "Energy uh, finds a way"
>why is it that only earth has life?
There is no way this can be true. It is very possible that life off of Earth exists even within this solar system. Some moons of the gas giants may potentially contain liquid water below an icy surface, and life may exist around thermal vents near the bottom of these sub surface oceans. This is possible because of the life that exists at the bottom of our ocean along the mid Atlantic ridge, which gains all of it's energy from thermal vents. Given the the way "life finds a way", it is almost guaranteed that some form of it exists elsewhere in the Universe, if not our own galaxy. Life that resembles a civilized species, such as humans, or even life that is similar to multi-celled life here, may not be very common, and we may even be alone in that regard.
