Aliens, and do they exsit?

Aliens are a very controversial topic, many people believe we are alone in the universe, and then there are many people that believe there are aliens.

I believe that we are not alone in the universe.

                                   MY REASON'S 

The first reason is, there are 1,000,000,000,000,000,000,000,000 planets in our OBSERVABLE Universe.
So that is only the planets we can see, how many more must there be, so the chances that there are not aliens in the universe is is next to nothing.
