The place to discuss debate whether their real or not,For one I beleve Aliens are real,I mean the universe is so big we have to have some other inteligent life right?

If alien life is anything like what it is here, I highly doubt "intelligent" is an applicable term.
But- yes- I do believe that life exists out there. The thought that this planet is the only one is pretty darn depressing, y'ask me.

I am pretty negative about the existance of inteligent aliens.
I know there are about 100 billion galaxies with about 100 billion stars. But here are my reasons.
1. You need a spiral galaxy.
There are three major types of galaxies, spiral, elliptical, and irregular. But only spiral galaxies have enough dust and gas to form planets. Elliptical galaxies don't have enough gas anymore and irregular galaxies are mostly too small. But in the universe, about 60~70 percent of galaxies are elliptical.
2. You need to get away from the center of the galaxy.
Near the center of galaxies, the density is much higher than anywhere else.
3. You need a single star.
You don't want binary stars where planets form. Too much heat, not very stable orbits will give no chance for a life to exist if a planet is formed around binary stars. Majority of stars are in binary systems, or even triple star systems.
4. You need a right star.
Too big of a star can't live too long to hold planet long enough. Too small of a star can't give enough of light and energy for life to start. Even though our sun is about the average size, this factor doesn't eliminate too much but it still eliminates quite some.
These are some of the factors just for some stable planets to take place. Having some life to form and developing into intelligent species is totally different story.
Why don't you throw a million puzzle pieces from a plane and wish for them to fit perfectly together when they land?

But that is simply going upon the assumption that physics as we know it and their effect upon their surroundings is absolute.
What's to say that life cannot form under an entirely different set of parameters?
Not to mention that the known universe cannot be accurately measured- as abstract that idea is- that alone can upset the odds exponentially.

I think this truth overrides the reasons you mentioned. 60-70 percent of the galaxies are elliptical? Oh, well, that just leaves a few thousand billion other galaxies then, which each holds a few thousands of billions of stars that as far as we know can have even more billions of planets where life is possible.
Considering the odds of only Earth having intelligent life in the entire universe, I must say that I believe it exist in other places. Maybe not even too far from ourselves (ofc thinking in cosmological distances).
