The idea behind probability is that the higher the number the greater the chance.
An example is you have 5 coins and you throw them hoping two land on heads. You then take 10 coins and you throw them, hoping 2 land on heads. Here, you have a greater chance of 2 landing on heads with 10 coins then 5. This goes back to the alien thing. Based off of the uncountable amount of planets, the percentage of another life for out there is very large.
Oh I know he isnt intelligent, but I meant him typing. I thought it affected reading, not really him writing/typing

Again, as a friendly debate.
I think you fail to realize the "special" circumstances that allows us to live on this planet. I might as well back that up with some facts.
First of all, We live in a fairly isolated part of the galaxy. Between 2 spiral arms of the Milky Way. We exist in a very small window called the "co-rotation radius" it pretty much means we don't get pulled into the more crowned arms of the Milky Way. If we were closer to stars, a lot more debris would be flying our way.
Also, without a Jupiter sized planet in it's position...the Earth would have been smashed by so many space debris there's no way we could live here.
In fact, even if we didn't have the unusually circular orbit we have around the sun our climate would differ so much, that life is almost impossible to survive on it. And astronomers have determined that the chance of a life supporting planet with our orbit and in the "habitable zone" is almost none.
Here's a direct quote from the American Astronomical Society:
"With this new information, it seems very unlikely that stable planetary systems, in which a small earth-like planet resides in the habitable zone, exist in any other galaxy in our universe. This does not even consider the other design parameters that are required for life to exist anywhere in the universe."
And that's just taking into account 2 variables of the MANY.
