Something that never ceases to amaze me is how everything began.
To start with, there was nothing on Earth but look where we are today. The human population is 7.8 billion, but where did we all come from? It took 200,000 years for the human population to reach 1 billion, but only two centuries later it is 7 billion.
There must have been one organism which created life, which created more and eventually, over thousands of years, will have then evolved to create different species. However, the question of where the original organism came from is still an unanswered question.
Take a moment now to go outside and look around you. I can guarantee that, no matter where you are, you can see some kind of biology. Whether it is a tree, some grass, a seagull flying overhead, or even a jumping dolphin if you are by the sea. Now ask yourself, 'If I was here, in this exact spot 4.5 billion years ago, would I see all of these different forms of biology?
The answer is probably no. It is absolutely awesome to even try and imagine how all this biology around you came to be.
Biology is everywhere, even if you are surrounded by a concrete jungle you can probably see a pigeon, some trees and perhaps some flowers near some cafes.
Now going back to the original organism. If that organism birthed all of the nature that we see today then somehow, you and I are connected. We all come together somehow and we are all connected, somehow. But how?
