I am willing to believe that yes, our souls are immortal and can reach places that even we cannot. But I believe that now, we’re simply in a setback from our true potential in terms of space travel. I think that it’s most certainly possible that we can build functioning stations on the moon, make trips to Mars, and so on, it’s all a matter of finding the right developments, which I don’t think are entirely impossible, I just feel that we are having setbacks right now, due to various issues on Earth that are holding us back. But I do feel, that there can be greater leaps made in the future to come.
If there are other 'similar' intelligent life forms on other 'habitable' planets, then maybe the setbacks are even part of God's plan.
Maybe we just aren't ready to encounter the other 'rooms' in God's house.
For the most part, the humans on this planet still act like spoiled children who hit other children for playing with their toys.
