Origin has a point.
We humans tend to ask questions like this. Why is the universe created so big when WE can't explore it all? Why did God create caves on a planet in an orbit around a star in a different galaxy if no human will ever see how magnificent they are?
My view on the matter is that God did not create it, because there is no God. The fact that the universe is so big and that the Milky Way galaxy is not at its center (and the Solar System is not at the center of the galaxy and our planet is not at the center of the solar system) tells me that we are not significant in terms of the universe's creation.
It's not all a show for us to admire. It is in our nature to admire and explore what we can, but this is not the reason the universe came into existence. So yes, there are caves and waterfalls and magnificent views and double-star sunsets and violent explosions and life forms out there that we will never encounter. But look at the bright side. There are probably a lot of life forms out there (with big teeth) that we don't want to encounter. So maybe we're better off. :lol:
So to your question: Why is the universe so big? The answer is: it just is...
When you say: "I'm not asking this from an egocentric point of view. Sorry.
What I'm asking is why did God create such a large universe?" you assume that God exists, that he created it and that we (humans) are God's favourite (or even the only one) civilization in the universe. And that everything was made for us. So Origin is right. We tend to look at the Universe from a very egocentric point of view.
Not against you in particular, SporeFreak, but we (humanity) still unconsciously think of the world in a "medieval" way of layers. Earth is center. The universe is elsewhere. We still ask questions like "is there life or intelligence in space"? Most people would agree that if we discover one intelligent civilization in space, we can safely conclude that there are more. But we have already discovered life and intelligence in space. On a planet called Earth. Earth is a part of the universe just as much as any other planet out there. It's only a couple of decades since scientists actually aksed the question if planets could exist around other stars than the Sun. Of course they do!
By now we are finally starting to learn: The Earth is not a unique planet. The Sun is not a unique star. The Milky Way is not a unique galaxy. We are not all there is and the Universe (or even the Earth) was not created for us to live in. We just happen to live here. But there was no plan, no intelligent design, no God that decided to create us and a universe for us to admire.
That doesn't mean that our existence is meaningless. Our existence and our planet is extremely important to us. But if we one day encounter an alien intelligent speices, don't expect them to accept that WE are the most important ones.
