Well, if there are billions of stars in an average galaxies, and there are countless galaxies in the universe, even if there is an odd of 1 to trillion, then the probability of having life forms in other galaxy systems appears to be good.
However, life-forms as we know on earth may not be duplicated elsewhere. Ours is carbon-based. It is not improbable for other forms of life to exist.
Because of limitations to speed of light, and hence to travelling speed, we, earthlings, may never be able to encounter alien life, as some galaxies are hundreds of millions of lightyears (a lightyear is the distance travel by light in 1 year) away, that is it takes light hundreds of millions years to reach us from that distant galaxy.
So even if the intelligent life-form on the outskirts of our known universe were to evolved a million years before us, and if such intelligent life-forms were to be able to travel at the speed of light, they cannot reach us in another hundreds of million years.
By then, our enlarged sun would have scorched our earth into an uninhabitable region, meaning all lives on earth would be wiped out.

Likely any two species that encounter one another in space WILL be separated by millions of years development-wise. Given the time scales involved, the chances of any two civilizations being at a level of parity are extremely low.
On the other hand, there is likely a weeding-out period where most civilizations die due to poisoning themselves or blowing-themselves up. We are an extremely young species.

But we can't break the speed of light, and it takes 4 years travelling at the speed of light to reach the nearest star. Even if life is plentiful in the universe, we probably won't ever know unless we find some form of it in our own solar system. I think the idea of aliens somewhere is extremely likely, but of aliens visiting us? Not a chance.

I suspect the universe is saturated with intelligent life. Its won't be like us though. In fact in 50 years we will be so different from what we are now if we met ourselves we'd think we'd met aliens. Its quite possible by the year 2100 humanity will have broadcast itself to the stars, not in spaceships but as organized packets of photons, neutrinos or... who knows!

Life stared over on Earth many times befor humans arrived. I think there is intelligent life in the universe. I'm just not sure we count.

What's weirder to think: That among the great vastness of space, in the billions of galaxies and trillions of stars in each, that we're alone? Or that we aren't?
Personally, I think there's something else out there.

Well just go out one night & look at rhe stars, & an answer may come to you after a while. If it don't just go back in & go to bed.
Thats about all the time I would spend on it.

What do you mean by intelligent? Do you mean Bush / Cheney intelligent?
I don't think "they" have found intelligent life here on earth yet!
