Why do you think God didn’t create the other worlds and the beings inhabiting them? The universe is enormous and we are now rapidly discovering far away planets. Remember when scientists argued that planets were rare?
God didn’t need to create a universe filled with billions of galaxies, each will billions of planets, just so we could look up at the sky and find nothing much else.
Where in the Bible did God promise us that we were the only ones? I think there are some old testament passages referring to God filling other worlds with angels.
Also, we know God created the heavens and the Earth. He created man and woman. In essence God created life, but I’m not sure the Bible says that he created all life everywhere in one shot, or that he created a universe in which life will not arise from his original creation.
The earth is not even remotely the center of the universe God created.
As a final thought, true God created earth and man, and even life here. But aside from the direct intervention of Jesus and occasional miracles, God has allowed things to develop in intricate ways on earth for thousands of years.
Why do you think God has not likewise breathed the spark of life elsewhere, and allowed that life to develop, for good and for bad, as we have seen it developing here on earth.
I’m pretty sure God didn’t approve of the Nazis but we had them and still have some. Why do we presume God has not allowed the inhabitants circling Alpha Centauri to also have free will?
He set his creation loose here why does anyone doubt he did the same elsewhere?
Please don’t try to anticipate what I think.
That’s what questions are for.
