where, in the Bible, does it specifically state that Earth is the only place where God created any life form????? .
The first sentence of accepted biblical text distinguishes the Earth from the heavens. The remainder of the biblical texts treat chiefly of life as known on this planet, and references the heavens occasionally with some detail as part of God's creation, but not as the predominant object of His works. That object is man, and only man. Not angels. Not animals. Not rocks. Not stars. To expect a specific biblical text that commands men to refrain from space exploration in the interest of finding alternate intelligence is to make a mockery of the purpose and intent of the biblical texts in the first place.
It is the total theme of the entire Bible: The “people for his name.”
The purpose of creation was to give birth to the people for his name.
You miss a lot when you don’t study the prophets.
