Imagine everything you see around you—the trees, the oceans, your phone, even the stars—squeezed into a tiny speck much smaller than a single grain of sand. About 13.8 billion years ago, this hot, crowded speck suddenly expanded. It was not a quiet puff of smoke; it was a sudden, violent stretching of space itself. We call this the Big Bang. In a tiny fraction of a second, the universe grew from nothing to something unimaginably vast, cooling down as it stretched. Fast forward about nine billion years to the birth of our own planet. Out of the leftover dust and gas swirling around our young Sun, gravity started pulling giant rocks together. They crashed and melted, eventually forming a hot, liquid ball of rock. Over millions of years, the surface cooled into a hard crust, water filled the basins to make oceans, and the stage was set for us.
“Our planet was once hit by a space rock four times the size of Mount Everest, but instead of wiping out everything, it actually delivered the essential nutrients that helped early life thrive.”

If a destructive space collision could actually jumpstart life on Earth, what other chaotic cosmic events might be creating life elsewhere in the universe right now?

Imagine a giant cloud of dust and gas collapsing in space. This collapse formed our Sun. The leftover scraps swirled around the young star, crashing into each other and sticking together like giant snowballs. Over millions of years, these rocky clumps grew larger and larger until they became the rocky planets we know today, including Earth. It was a violent time filled with constant space collisions.
When Earth was very young, it was not alone in its orbit. Scientists believe another planet, about the size of Mars, crashed right into us. This ancient planet was called Theia. The impact was so powerful that it blasted huge chunks of Earth's outer layer into space. These hot, rocky leftovers eventually clumped together to form the Moon we see in the sky tonight.
Many people think life started in the deep, dark ocean. But scientific research suggests a different story. To build the basic building blocks of life, you need ultraviolet light from the Sun. This means life probably started on land in warm, shallow pools or volcanic hot springs. Here, sunlight and water mixed with chemical ingredients to create the very first self-replicating molecules.

Perspectives
Enter a viewpoint. Notice what it reveals, what it leaves out, and whether it changes the question for you.
Scientists view the start of the world as a natural chain reaction of physics and chemistry. It began with the Big Bang, followed by gravity pulling dust together to make planets, and finally chemistry sparking life. There is no need for magic in this view; everything is explained by universal laws. By studying rocks, light, and space, we can piece together this beautiful, logical puzzle of our own cosmic history.

No AI help here — no suggestions, no autocomplete, nothing finishing your sentences. That is deliberate. Working out what you think is effortful, and the effort is the part that changes you: reasoning is trained like a muscle, and a muscle that is always carried gets weaker. Let something else do the thinking and you keep the answer but lose the capacity to have reached it.
