I'm guessing we won't meet aliens even if they exist

Universe is just too big and once you approach the speed of light, funny things happen with time

Even at speed of light it takes 100,000 years to just go from one end to another in the milky way. And that's just one galaxy among the billions out there.

And we aren't even counting the vast amounts of empty space between galaxies where in future, rate of expansion of the universe can be faster than the speed of light itself
