You know that Christ was sent to Earth to redeem His people. That makes you assume that there is life only here. Yet, the same struggles of life and Redemption could have easily played out in other places. Just because it occurred here doesn’t mean we are alone.
I agree.
The counterarguments are: 1) Jesus is God and exists in Eternity rather than in time. He could have died in what would seem to us as multiple times and locations, but to Him is just once from Eternity's POV.
2) Wasn't it also unfair for Jesus's travels to be limited to His neck of the Middle East? Yes it was part of the Roman Empire which ultimately led to His teachings traveling far and wide. But they didn't reach the New World for over a thousand years. Nor did they reach to China, India, Australia, etc. There are stories of at least one apostle getting as far as India, but even so he would only have been able to visit a relatively small area within India leaving most of the citizens in the dark for millennia. And what of all the people who were born, lived, and died thousands and tens of thousands of years before Jesus walked the Earth? How fair was it to them not to hear the full message?
