This sounds just like Hindu philosophy. It is hard for me to imagine the universe to function by itself. For example, the planets are in their own orbits. If their motion is altered even by a fraction, it will affect the weather pattern of our planet.Life will become extinct if the temperature shifts outside the norms. Our planet maintains the necessary conditions so that plant and animal life will be sustained. There has to be something governing the entire universe. There was abeginning like the Big bang. There must also be an end. In between everything is sustained. How?
Textbook argument from incredulity. The universe is infinite... I am not at all surprised that a planet exists that supports life. Just because you can't imagine something doesn't mean it isn't so
