If life randomly developed here, it could develop somewhere else. What form it would have, and how intelligent it would be, who knows?
Either way, the odds of it ever showing up here are about as close to 0 as possible. Unless it had an amazingly long life span, it would need a faster than light form of travel, and I mean a lot faster, like several times the speed of light. The theory of Relativity, old E=MCsq, suggests this isn't even possible. And even if it were possible, the amount of damage even a speck of dust could do an object moving at that speed, would make a journey that far, at that speed, extremely unlikely.
Some believe that worm holes or other anomalies can be created to avoid all that, that is theoretical. But even if it were possible, it brings up the other issue of why would they come here in the first place. The universe is so vast, that even if one had the technology to navigate their way here, the odds of them coming across this spot in the universe by random chance is again about as close to 0 as you can get. The only reason they would come here specifically would be if they detected us. Because we are not sending out signals at speeds faster than the speed of light, anything they detected from us would be thousands, if not millions of years old, by the time it reached them. If they had the tech to get here, they would have to be aware of this. Even if it interested them enough to make the trip, we will all be long dead before they even get the signal.
So life on other planets, and even intelligent live on other planets is plausible, but I don't think you will ever get the chance to shake their hand.
What is your opinion of aliens?
