We are based on carbon, and use oxygen. I believe there are a few theories that silicon and ammonia may also work.

Silicon is much less versatile in the different kinds of molecular compounds it can form, and most of them are unstable. So life based on silicon would be extremely rudimentary and very unlike to evolve beyond the simple capacity to reproduce. It would be hypothetically possible on planets with very high temperatures, but the idea of any intelligence of complexity of life forms would be extremely remote.

Could be there isn't any.

I mean, think how advanced we'll be in a 1000 years. In the scheme of things 1000 years ain't nothin'. The universe benin' 15 billion years old and all. Surely if there were "advanced" folk out there you'd at least think they would use radio technology 500, 1000, 5000, 25000 years ago.

So how come we ain't found nothin'???? Maybe we're it.

25000 light years can still be considered in our neighborhood, or even just our back yard when you think of the size of the universe.

That is a good point and one which there is circumstancial evidence to support it.
However, science has not got there yet in its quest for ET life, so we will have to wait a few years until they get around to considering it.

Unstable where? On Earth? Maybe, but not necessarily on another planet. How do you make such statements unless you know the environments on all the possible planets which may evolve a silicon-based lifeform?

NASA has, and their scientists have found water, methane, and ever supposedly microbes on rocks from Mars. Those are the things which are documented but no-one wants to pick up the stories and run with them at the moment. I know this is not much as far as life goes, but if there are these building blocks, then there may well be larger forms of life. I have my own beliefs on this, but what I have said here is the official view.

What I find amazing is that jack-asses like Sagan can't even apply the simplest concepts of logic.

I take issue with this characterization of Sagan. He may be wrong in this instance and other instances but he was a scientist who always ended his hypothesizes with "I could be wrong" and doesn't deserve such a designation.
The cast of Jersey Shore are jack asses. The makers of movies of the same name are jack asses.

I think the best way to confirm if there is life out there is to keep working on our telescopes, keep making them stronger. Then time won't necessarily be an obsticle since telescopes are looking back in time. If we could ever get our telescopes strong enough to see what is going on at the life level on planets and even refined enough to see spacecraft, we could watch the whole movie of the universe play out before us at will.
