Scripture is, indeed, silent about life on other planets.
It just notes that Christ created all that was created and that without Him, there was nothing created without Him.
God knows Humans are of a curious mind and would wonder about the possibilities that his “living creation” extended beyond our planet. If he said it didn't, and that what we see is it, then I would take him at his word. But he was silent about it. So for me, I guess I will find out the day I am taken home. No doubt, the wonders of his Kingdom and the Universe is far far beyond our wildest imaginations.
Not really.. “In my Father’s house there are many mansions...”
In Genesis 1:26 "...God said: 'Let us make man in our image, after our likeness...."
Some speculate that this is the royal "we". Others think God is speaking to the angels. One rabbi has said He was talking to the animals. But I wonder, as a fierce monotheist, that He wasn't communing as it were, with other intelligent life even then elsewhere in the cosmos, also "made" in "His" image.
