I’ve always thought it a little bit arrogant to assume that we are the ONLY advanced lifeforms in the entire universe. In our own galaxy, alone, the Milky Way, there are millions of other solar systems with their suns, and beyond the Milky Way, millions if not billions of other galaxies with their millions of solar systems and suns. In all of that, to assume we are the only advanced creatures is a very far stretch.
One day, we just might develop sufficient technology to detect and perhaps communicate with advanced beings elsewhere in the universe.
I can’t imagine the Ultimate Creator having only created earth and the creatures on our planet. To assume such is to place limits in our minds on God’s power and infinite abilities, not to mention his love of life and living things.
Beyond all of those physical universes may be one and possibly more spiritual universes, all created by One True God.
