There's could be millions of planets bursting with life. But they're just like us with no idea how to traverse the universe or are just wild animals or plants etc with no intelligent life as we know it.
Yup, a lot of being still face the physics of whatever they're dealing with at the end of the day.
I personally think that the “we’re doomed” if we make contact mindset is overblown.
It’s rooted in egocentrism when you think about it: “all other alien races must be like White colonizers on Earth”
Also, resources aren’t a problem…the universe is big as fukk / if they can get here they can surely get to other uninhibited planets that have even more resources.
I'll add to this: who even says it's
humans who make it to the other planet from earth.
Maybe Real General A.I holding human collective intelligence does.
Remember, if we follow the course of history:
13.8 billion years ago the Big Bang
Rocks collided for 9.2 billions of years (and are still colliding)
4.6 billion years ago enough rocks collided in a special way to form earth.
At some point water came to be after enough collisions
4 billion years ago cells came to be
At some point these cells formed fish
At some point these fish got on land to become mammals
At some point these mammals became humans with five senses and a brain
Now we as humans are observing the Universe through our senses and thinking our way through things in this environment
We're the Universe observing itself and now we see other planets/galaxies and want to traverse/get to them.
However, we're limited physically but if we create an Artificial Intelligence that resembles us and too is observing the universe, we can "transport" our human consciousness with a machine/machines that can actually make it to other parts of the cosmos. We may not be able to make it to other planets before the Sun super novas, but our consciousness via A.I may.
We don't really get a final say in
Universal matters and who gets to make it where, humans, like those mammals and fish we're here because rocks smashed together enough to form our consciousness/senses after all.
