Closed environment

Earth is working on different principles as other empty planets.
Our organic paradise has got everything what is needed for life. It's acting like a closed environment with strong protection toward outer occasions. Atmosphere and biological environments are protected by a magnetic shield. Inner space is working like living organism with strict natural laws.
Everything happened on this place and staying there within cycle of life. The biological environment, where animals with humans live, is protected by atmospheric structures.

When we look on other planet in our Solar system, they sometimes have thin or toxic wild atmosphere. Sometimes are bombarded by asteroids and meteoroids. Or hot and cold environments are in contrary to habitable properties. On the other side our Earth is organic paradise in right position within Goldilocks. It can't be designed better by God.
Evolution didn't stop on our planet but actually has continued into organic evolution and designed variety of species. Earth has got everything; water and oxygen in large extent, so flora and fauna world could flourish into current state.

Sun is our friend. Not strong, but also not weak to shine and offer energy for launching life. We have colder or warmer regions in the atmosphere and also on the ground or above the surface in oceans. Therefore, life is also flourishing and it's full of new forms. For ages weather has been acting in symbiosis with natural worlds. In short, Universe created all properties on Earth suitable to act like one closed system.

We know Universe offers four fundamental forces; gravity, electromagnetism, strong and weak nuclear force. But on our planet must be another force acting to create this close system with strict natural relationships.
We live in organic paradise and we know Universe is not organic paradise at all. It's empty space among galaxies. Or it's a dangerous flaming environment.
How come we really live in organic paradise lasting for ages?
Yes, Earth has certain protection and the right amount of energy falling down on surface. Our planet lies in habitable zone and contains of right mix of organic chemical elements. But is it enough to describe by this?
Natural forces have been learning over ages to live in symbiosis, create sustainable biodiversity. Atmosphere giving us water from sky to the ground. So, life could thrive everywhere. Our Earth is also one huge symbiotic environment.

Whether we want travel and explore next closed planet Mars, we come to conclusion, there is nothing like planet B. We haven't found yet another planet like Earth. We can't change Mars into Earth once because it lacks of natural forces present on our planet. Sometimes we should be more on the ground and take Earth as only right place to be for us, humans. Because Universe created this closed environment with plants and animals for us, humans.
