Why This World, We and Everything Exist?

What is the ultimate reason for the existence of this world and everything in it, including us? There are innumerable creatures, it is impossible for everyone to know them. All these creatures also have a life that they spend in this world and then eventually end. But man is the only creature that has been given consciousness. Has anyone ever wondered why there is such a difference between all these creatures and man? And then why isn't this thing given to the same creature only to the rest of the creatures. This means that in fact there is a special purpose for this human being in this world, otherwise the rest of the creatures are the same from the first day till today. Yes, man. Everything else seems to be designed to entertain and benefit or harm man. Man is the consumer of all of them.

He is the only creature who believe in religion.
