Existence - we exist as the particles of matters, created by the nature's creativity. But can you say that there's a proof that Nature actually exists? The fact that 17 billion billion years ago things happened and created a space that grows itself and spheres that even light can't pass, and all this happened on its own just by a huge explosion gives tensions to the scientist all over the world. 

Nature, that is just a word we use for our surroundings, an abstract noun. Did it created all this? In other language, did god created all this? No, I don't think so, it was all just a huge setup, by someone omnipotent. 

"Changes have been an important aspect of the Human Society. People were born, people died, people were killed, people did suicides. And things changed from the way they started. Men was meant to be mortal. That's it. That's what god thought. That was the difference between the two. People were meant to struggle." 

But really, was it the god who created it? Not any other thing? Its unbelievable though. Because of we're going to search the beginning of the universe, we should start with the creation of humanity first. 

Who created the animals the birds, the so called aliens, the humans itself? Who created them?
