Billions of years ago, Our Earth's creation was started. Many things have changed till then to now, And the key named is which has changed the earth and living beings is evolution. our was started in water in the form of cells or microbes. These cells started multiplying themselves and converted in living organisms, these organisms are started evolving themselves. By evolution they was converted into water animals. On one side in water there were life but on other side there were only trees which was not fully developed. The animals which are in water was started coming on the lands and started evolving themselves for land. After this many evolutions had taken place in humans or other animals. But the biggest question is, Only we are in the world which has been created by nature. Seriously on this question my ans is NO. First we have to understand that where we stands. Our Earth is in the solar system which governed by the sun. In our solar system there are eight planets including Earth. Let's start that where we stand.
our galaxy is milky way. In our galaxy there are millions of stars in which the one star's of us. Actually these millions of stars form a one galaxy milky way. After milky way galaxy there are three four galaxies which are closer to our galaxy, one is Andromeda galaxy. like this there are billions of galaxies which form an universe. After the universe there are more thousands of universe which known as multiunivers. So just think there are more than trillions of planets similar to earth only so why we should not accepting that there are multiple planets that same as our earth, So there is very huge probability is that there must be Aliens. And I believe that Aliens Are exist.
