You know, we all live on planet Earth, and on Earth there are many countries, many people, and many, many types of animals.
You can see fishes in the sea, and there are so many different kinds! There are very small fishes, there are big fishes, there are sharks, there are whales. There are such tiny fishes which you can even hold on your tiny finger, and then there are fishes which can gobble up ten people at the same time!
Then you come on land. There are small insects like ants, then there are bees which can fly, there are birds, there are big animals like giraffes and elephants, and then there are small animals like mice.
So this whole Earth is full of people, full of living things—animals, insects, birds, fishes—and all this has come from somewhere. Nobody knows where it came from. Who made the first person? Who made the first elephant? Nobody knows. We don't know.
And it's all over. There are so many, so many types of living things, and there are mountains and trees.
So when human beings started getting intelligent, they started thinking: Where did this all come from?
And then some people said, 'Oh, God put everybody on the Earth.'
But others said, 'Okay, God put us on the Earth, but who created God?'
Nobody could answer these questions. Everybody just believed it happened because it's very difficult to answer these questions. Why are human beings intelligent? Why can they speak? What is the reason?
And then what happens? What is outside the Earth? You see the stars.
So then, 300 or 400 years ago, people got telescopes and they could start looking out into the sky, and they started discovering things. And so they made one theory. I call it a theory because nobody knows if it's true or not. But all the science points to the fact that this is the best evidence, the best story.
You know, if you go outside the Earth and you keep going, going, going, going, going straight, the universe doesn't end anywhere. It is ever-expanding. It is so mind-boggling that the universe keeps expanding. There is no end to the universe, because even if there is an end, there has to be something beyond that, right? It cannot just be an end. It is endless.
Because what do you say? What is there if it ends somewhere?
'Yeah, it's a circle,' some might say.
Who knows? But what is outside the circle? Some people say it's a circle which goes into itself.
So the best theory is this: billions and billions and billions of years ago—many, many billions of years ago—there was nothing. Absolutely nothing. No planets, no Earth, no people, no stars. Nothing. Billions of years ago.
And then there was one single point where suddenly there was one tiny, tiny point, and it—BOOM!—it blasted.
And it blasted so much that everything came out of that small, tiny particle. It was condensed, and it broke, and BOOM! And it kept expanding, expanding, expanding.
And then out of all that, Earth was formed, the sun was formed, all the other planets were formed, the stars were formed. It's called the Big Bang Theory—that it banged.
And then after that, many, many planets were forming, and then Earth itself was revolving around the sun like this. Everything was black, and then it was rotating around the sun.
And then, just by chance, the Earth was just at the right distance from the sun that it had the right climate, that it had the right conditions. It had water. It has an atmosphere.
And then the first living organism was born here, which is a single-celled organism called the amoeba.
And from there, slowly, slowly, the first fishes came into the sea. And from the fish, then the tortoise came. From the tortoise, the monkeys came. And from the monkeys, slowly, slowly, the human beings came.
And initially, the human beings were like monkeys. They were just living in the jungle, in the caves. And over time, they got smarter, smarter, smarter.
They started building things. They started hunting. They started growing fruits and vegetables. Then they could build cities, they could build roads, they could build cars. They could make rockets which can take you to the moon. They made medicine so that when you get sick, you can get better.
And that is the story of human progress. And all this has happened over the last 10,000 years.
