The Earth is a magical planet. A miracle planet.
There are hundreds of thousands of things which could have happened to prevent the Evolution of human life from occurring on this planet. But evolution somehow managed to skirt these problems ... and (by sheer luck or divine intervention) here we humans are!

Earth is about 4.5 billion years old.
The Earth forms in the same explosive event which forms the Sun.
(The Big Bang, 9 billion+ years earlier had formed only Hydrogen and Helium. This more recent, local explosive-event forms all the heavier chemicals needed to build Planets ... and eventually Life.)
The Earth is molten rock for 100,000,000 years. The sky is red from thick carbon-dioxide and hydrogen-sulfide in the atmosphere. The solar energy reaching the Earth is weak, the Sun a dim light in the red sky. Over time most of the heaver elements like Iron sink from gravity, and the lighter elements and compounds like water rise to the surface. This molten iron core creates magnetic fields around the Earth, deflecting deadly solar winds up and over Earth and safely into space. The sky stays red.
The Earth is pulverized by meteors and comets, still flying wildly about the young solar-system. These bring to Earth large amounts of Water, and small amounts of Amino Acid compounds. Heat evaporates the water, and it rains relentlessly for millions of years till 90% of the Earth is covered by water. Impact with Earth does not destroy the Amino Acids these meteors and comets carry, but fashions peptides (larger compounds). And millions of years of trial-and-error, or sheer chance recombining molecules in the huge sea, produce proteins and eventually bacteria cells. The sky stays red.
Granite rock forms, which makes possible the formation of continents. Early single-celled life is sulphur-based and oxygen-intolerant. Single cell cyanobacteria reverse this and start binding nitrogen, utilizing the Sun's energy in this chemical process, and giving off oxygen as a bi-product. After 1 billion years of pumping oxygen into the atmosphere, the skies turn blue. The continents drift together, colliding, forming one supercontinent. Then a massive sheet of ice covers the entire Earth, for 50,000,000 years, killing off all life on Earth.
Almost all life. (Narrow escape.) Volcanic activity begins to tear the supercontinent apart. Ice retreats to the poles. The planet sustains a heatwave. Multi-cell life develops in the oceans - in a mad rush. The ozone layer develops around the Earth's atmosphere, as a UV-protective shield, so now life can begin to develop on land.
Then massive volcanic eruptions blacken the sky, cool the warm Earth, and kill off 95% of all species. Another super-continent forms and breaks apart. When the dust settles, dinosaurs develop and rule the planet for 170,000,000 years. And they perhaps still would be, except for the conjunction of two simultaneous catastrophes - a massive volcanic eruption in India, and a huge meteor hitting Mexico. Dinosaurs and 70% of all living species become extinct.
But a mouselike mammal emerges and evolves. 2 million years ago, one of these mammals stands upright, able to run a prey to death. With ice ages, this creature learns to diversify its diet, and out-compete primate competitors. 10 thousand years ago, this creature intentionally begins to alter the ecology of the planet. 2,600 years ago, this creature begins to be able to recognize the difference between Internal and External reality - this creature is a creature no longer determined by genetic laws, but is able to make conscious decisions. This creature no longer lives in a dreamlike blur.
God is born.

Fascinating story. Right?
(Beat this creation story, Genesis-1 ... !
You can't, can you?)

Quite a miracle that we are all here. (So many things that might have prevented it.)
But ... what a story we have to tell!
What a story we have to tell.
.....ferget about it.
