If I understand your point is that God created all life only here on earth. Again please show me chapter and verse where God stated that He created all life and only here on earth. All life here on earth was created by God does not equate to God created life only on earth.
I believe the Bible, and thus God, is silent on the issue of life on other planets and thus leaves it open for discovery.
I've given you a mathematical exercise you can do to at least form a qualified opinion, all YOU'RE doing is, what if, (and) the way I see it.
What if means nothing, and the way you see it is totally dependent on the Marxist education you've received without EVER going to the scriptures to see if these things were true.
You ask me to prove God didn't create other worlds ?
YOU prove he did.
Actually, “In my Fathers house are many mansions, if this were not true I would have told you so.”
