Even at the speed of light, you would still have to live to a very ripe old age to ever reach your destination. We have a long way to go before we can come up with a propulsion system that can do even .1 of lightspeed. Thats 1/100th. That would mean about 1270 years later, a generational ship could make it IF the training cycle is complete and the resulting generations can preserve the knowledge of how to set down.
If only a tiny, tiny tiny portion of them have planetary systems, say 1 for each one billion stars, then there are 10 trillion planetary systems in the universe.

Even if you apply a huge coeficient of error, there are planets that never end!
I think there was a couple of other things, I can't recall right now.

In any event, it will prove interesting as our planet-detecting technology improves and provides new discoveries.

It was said that it would be nearly impossible for us to meet another intelligent civilization in the Universe, because, if they are made of hostile states (like ours) and they are intelligent, they will discover uranium eventually and will exterminate themselves quickly after.

Maybe; consider if a virus was so lethal as to utterly destroy its host species, then the virus would die out too -- end of the line from an evolutionary perspective. Better for a virus to not kill so quickly that the host species is unable to reproduce. From the virus' point of view that would be a better design -- and from an evolutionary perspective, that strain of virus would be more likely to survive, propagate, and mutate (and if selected, evolve...).
