You said it yourself, we don't know that there's other life out there. More to the point, we don't have any evidence to think it is probable or even possible. What information do you have that, in principle, abiogenesis must be able to happen elsewhere? What information do you have that, if it is possible to occur elsewhere, the degree of likelihood is less than the number of stars?
What those "simple laws of probability" you talk about actually tell us is that if we can't fill in the variables then we can't know what the probability is. Do you know what the likelihood of abiogenesis occurring on an Earthlike planet is? If you do, please stop holding out on us and go claim your Nobel prize. If you don't, then it is unscientific to speculate, you're just guessing.

Why haven't we heard anything from the realtors yet?

I'd feel nothing but sympathy for any other alien species that will have to come into contact with the human race in the future.Hundreds of new planets have been discovered by Nasa's new space probe, sparking new hope of life outside our solar system.
Up to 140 of the newly-found planets are rocky and Earth-like containing both land and water, conditions which could allow simple lifeforms to develop.
The Kepler probe - which constantly monitors more than 150,000 stars for tell-tale signs of planets orbiting them - also may have found five new solar systems, Nasa said.
I would bet money that if we ever did find another life, even if it was intelligent but not as advanced. Exploitation would most likely soon follow.
We can barely control ourselves on Earth, imagine us in space. o.O
Saying that, find other planets that are similar to Earth. Gotta have an escape plan for when we really **** up.

It's immensely unlikely that there is any reason why abiogenesis could only happen once - after all, deterministic mechanics (and pretty much quantum, too) says that any act can on principle always be repeated. However, we don't know the probability that abiogenesis has only happened once. It could be we're a one-in-a-googolplex lucky chance, or it could be theres at least one form of life per star. I'd tend closer towards the latter, but it's impossible to tell.

Granted that we haven't necessarily done anything giving us a reasonable claim to the whole moon, BUT...
There isn't a country on Earth INCLUDING the US that could go to the moon within one year. There is definately no country on earth that could send as many men to the moon as we did within the next ten years other than the USA itself, and if we did it would require a new and serious committment to space exploration.
Heck, 3/4'ths of the world couldn't even get a small satellite in orbit if you gave them the next ten years to do it in, let alone put an unmanned probe on the moon, let alone send a manned vessel... let alone send several as we did.
But if we don't get off our asses and get busy, in 2100 the Chinese are going to be mining radioactives and rare metals from the asteroids, and scooping He3 from Saturn's atmosphere, and telling us to buzz off 'cuz it's their solar system...

I was discovering that life just simply isn't fair and bask in the unsung glory of knowing that each obstacle overcome along the way only adds to the satisfaction in the end. Nothing great, after all, was ever accomplished by anyone sulking in his or her misery.
