Additional intervention

Goldilocks zone doesn't guarantee that life is capable to emerge on the planet.
Might particular conscious intervention have caused that life continuously launched on Earth.
Some specific driving power.
Some special order in Universe causing life to appear.
We observe many exoplanets in Goldilocks zone but probably without life on them. Even Earth could stay empty without life. But did not happen. Something special additionally happen to our planet.

Might small forces with intervention form side of Universe caused life to start and spread all over the sphere.
Enforcement of life was not an easy process. For particular long time no big changes happened. Life firstly evolved slowly. From point zero to one made great conscious step.
Launching a consciousness on microscopic level. Transforming the wisdom from side of Universe on our planet with continuously creating new level of conscious processes.

Conscious additional intervention we can find within laws of physics and chemistry throughout all Space and whole ages. But new conscious step as creation of biochemistry requires push driving force forward. To understand environment, evaluate properties present on our planet. Then life could be launched.

Universe is uniform in general. Despite there is no the same star or planet, we live on the most specific and magnificent place in all Universe. Additional environments, living ecosystems with multicellular life. Wherever you look, you see something alive. This is unique. It is happening only once per ages.

Maybe once we find life on other planet, even within Solar system. If we are fortunate. It will give us many answers about conscious processes like evolution is.
Evolution got many faces. The processes of development inorganic worlds throughout Cosmos and our organic paradise on Earth.
