What are the odds?

What are the odds that we are the only life in the entire expanses of space?

Well here are the figures

There are about 10 billion galaxies in the observable universe! The number of stars in a galaxy varies, but assuming an average of 100 billion stars per galaxy means that there are about 1,000,000,000,000,000,000,000 (that's 1 billion trillion) stars in the observable universe!

So in my opinion the odds that earth houses the only life period seems to be very unlikely. 1 billion trillion , that is an amazingly large number.
