so we know in space that galaxies are pulling away from us and that the universe is expanding, and we know that there are people that are actively searching for life in space
i would think that there is a possibility that there is intelligent life in space, unfortunately it may be in the cards that we will never interact nor discover them since there is an expanding universe that is expanding at such a great speed, it would be impossible for us to ever seek out life and discover it
then i started thinking that as humans, maybe that is in the cards for us? maybe it is the same card that hypothetical "intelligent" species were also dealt because if we were to discover each other and even potentially work together, it might not be a good thing for the "universe" as a concept, imagine if we found out about each other and worked together and developed technology to travel faster than the expanding universe? suppose the multiverse theory was true, imagine all the stuff that'd get fucked up
i was reading some stuff yesterday about multiverse and the big bang and an interesting theory is that "the big bang" happens over and over again and that the cause of the big bang could have been two universes slamming together
seems cool, the universe is especially interesting because of all the stuff that could potentially happen, and i say "potentially" because given the size of the universe and "time" anything can happen
gonna check it out been a while since ive watched nova
space is cool until you realize that is an ever-expanding void then it starts to get strange and spooky

We're not searching for life in other galaxies, we're searching for life in this galaxy. We've got 4 billion years to search for life in this galaxy before the Milky Way and Andromeda galaxies collide and form a new galaxy, and assuming our solar system isn't ejected in the process, we'll have billions of years to explore that new galaxy. That is of course assuming that the human race will manage to stick around that long, because unless we are going to be around for billions of years then the expansion of the universe does not fucking matter.

Then your post make no sense. > unfortunately it may be in the cards that we will never interact nor discover them since there is an expanding universe...
If we're not searching for life in other galaxies, this has no effect on us.

meaning no matter where we search, the amount of energy needed to travel those amazingly long distances, (unless we somehow figure out how to travel at sub-light speed) its just improbable because since the universe is expanding, it is expanding at such an exponential speed (greater than light) we would never reach the "life" anyways

Which is not a problem as long as we're searching in our own galaxy. Even if we invented warp drive and could travel at thousands of times the speed of light, most galaxies are still completely out of reach even if the universe was not expanding.
You do raise an interesting point, however. One that Neil DeGrasse Tyson has brought up before. When the universe does expand to a point where galaxies can no longer even see other galaxies, all galaxies in the universe will essentially be causally disconnected. It will become as if each galaxy is its own universe, and observers and explorers of that time period will have no way of knowing that other galaxies ever existed. It makes me wonder what opportunities to observe we may have missed in the 13 billion years leading up to our own existence, if in fact the universe is that old.
