@ragingloli ” Life is not such a special thing, in terms of composition”
I know life is not such special thing but it doesn’t explain why certain planet,like this Earth,need such particular useless element to thrive in it.You said no reason needed to explain this one,what happen is just happen. But every element of our planet were formed because each of them serve a/some purpose for each of their respective planets.
Can you imagine why a planet such as Mars need to create such formidable atmosphere? (Yes,it used to be formidable) Does it serve any purpose for the survival of its planet? I believe you know the answer.
The problem about the religion-based theory to solve this issue is really different from this alien theory (I’m not insisting that alien theory is the fact of the issue),we know that religions are explainable,we know the truth behind it,thus make it inappropriate for scientific issues. This is,of course,different from the theory about aliens,we don’t know about them,we can study about them,but they pose the ‘higher’ potential to explain the life source issue on our planet. Aliens and any related subject about them are science-fiction,if not completely scientific.
If you bring this problem to the next level of life complexity you could learn that every life have a purpose on this Earth,they form the symbiotic relationship with each other and create the main/very first foundation and cycle in nature.
You can say that this Earth need such ‘food competition’ (as one of many other examples) for all life form to preserve its vitality in the galaxy,please don’t mix this particular issue with the ‘interference of human’ since we know about Earth and how to manipulate it,but we used to be manipulated by Earth. Can you imagine our Earth will survive without the purpose of each life on itself? If there’s no forest to produce enough CO2 and It will thicken the Earth’s atmosphere that may lead to destruction,or even elimination by ‘outer’ elements,such as asteroids. Even a single species such as rodent species have a serve a purpose on this earth,helping the plants. You can see that they’re all correlated one and another,with the Earth as the foundation of the activity. I believe every life serve a purpose on this Earth,as we ‘coincidentally’ serve the Earth,to preserve it.
