Fact: There is matter. This matter is made of chemical elements, ranging from H (hydrogen, the lightest element in the Universe, atomic weight 1) up to the far metallic elements, with atomic weight 100 and more.
Hydrogen makes approximately the 74% of all known matter, helium 24%, and all the others follow. The heavier elements make life possible; life is based on water, nitrogen, carbon, etc.
On a night without clouds if we look at he sky, we essentially see stars. Stars are built essentially with hydrogen and helium; during their life span the stars produce heavier elements in different manners, even when a star dies in a huge explosion.The explosion itself builds and ejects all this matter all around.
If this sounds simple, you're right; in fact this description is too simple but gives you an idea; I'll post something more accurate later on.
Fact: Everything you see, my body, your computer, the mountains and trees, almost everything you are accustomed to deal with is made of matter that comes from stars dead billions of years ago. This fact is a direct consequence of how Universe is and how it works.
We can say that when we think about the Universe, our brain, made also of those heavy elements, is a piece of Universe thinking about himself.
We, the Universe, are alive.
