I’d think the Good Lord would not have put all these stars and planets in the universe if He didn’t intend us to go out there someday. Just my opinion.
"To consider the Earth as the only populated world in infinite space is as absurd as to assert that in an entire field of millet, only one grain will grow." -- Metrodorus, 4th c BC Greek philosopher
"Heaven and earth are large, yet in the whole of space they are but as a small grain of rice. How unreasonable it would be to suppose that, besides the heaven and earth which we can see, there are no other heavens and no other earths." -- Teng Mu, 13th c AD Chinese philosopher
Possibly, but not in our current situation, ie when the universe is still in its fallen, damaged state.
We will get there the same way He is able to. Well the believers will, anyways.
Maybe He intended their inhabitants to come here.
