Where did the Earth come from? The Miracle of life.

In a wonderful short video, entitled The Most Astounding Fact, astrophysicist Neil deGrasse Tyson, in his inimitable way, answers the question – Where did the Earth come from? He talks about how the guts of the Big Bang we scattered, and the photographic depiction is incredible.

What is the Universe?

The universe is all the matter, energy, and space that exist. We can observe only a part of it – the observable universe. The entire, universe, including the part we cannot see, may be infinite.

Where did the Earth come from?

We know how the Universe and the Earth was formed. But

The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began. … The matter that spread out from the Big Bang developed into everything in the universe, including you.

Our Milky Way Galaxy was once thought to comprise the entire known universe. Today our universe encompasses many billions of galaxies, and its history can be recounted back to its earliest moments.

Our universe began with an explosion of space itself – the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies. Galaxies collected into groups, clusters, and superclusters. Some stars died in supernova explosions, whose chemical remnants seeded new generations of stars and enabled the formation of rocky planets. On at least one such planet, life evolved to consciousness. And it wonders, “Where did I come from?”

What came before the Universe?

We were designed as hunter gatherers, not to understand quantum physics.

Therefore, it seems incredible, when our brains have been wired to believe everything was created at some point in time, that in fact the universe was created out of nothing.

So what came before the Universe? As physicist Lawrence Krause says. If there were no Laws – no Space – no Time – no Particles, there was nothing. Therefore, the Universe we know came from nothing.

A universe popping into existence out of nothing is so bonkers that scientists had to be dragged kicking and screaming to the idea. But the evidence is compelling. The galaxies are flying apart like pieces of cosmic shrapnel. And the heat of the Big Bang is still around us. Greatly cooled by cosmic expansion, this ‘afterglow’ appears not as visible light but principally as microwave radiation – the ‘cosmic background radiation’, which was discovered by radio astronomers in 1965.

The Origin of Human Life

So, who are we – humans. And where did we come from?

The origin of human life is known to be in Africa approximately 200,000 years ago, and man evolved from his ancestor, Homo erectus ‘upright man’ in Latin. Modern humans originated in the Rift Valley, aka the cradle of mankind .
