Mathematically There is Zero Life in The Universe...!

Correct me if I am wrong but,

There are anywhere from 200 to 400 Billion Stars in our Galaxy alone. Each of these stars has the possibility of having Planets revolving around them.

There are approx 80 Billion Galaxies in the observable universe.
In all The observable universe contains about 3 to 7 × 1022 stars (30 to 70 sextillion stars) Each of these stars again, capable of orbiting planets.

If we are to believe that Planet Earth is the only planet with life on it, intelligent or not (which many people still do ;)) then by rounding off to the nearest whole number which would be rounding down, we we would be forced to arrive at zero.

There is ZERO life in the universe...this means you!!!

So next time you are having the discussion of whether or not there is life in the universe you can tell them no, not even on planet Earth. :D

I have added this Quote from the Hitch Hikers Guide to the Galaxy posted by Pazcat which summarizes what it is I am trying unsuccessfully to get across ...

It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination.
