In the Genesis story, the Earth was created on Day 1 before all other planets, stars and our moon etc on Day 4. Earth is unique and is at the centre of all that God created. And that uniqueness is centred around the creation of mankind.
In Peter 3:7-10 it is stated that God will destroy this present universe and create a new heavens and Earth. Everything in the entire universe will be destroyed and that includes Earth. If one believes in intelligence elsewhere in the universe, that would imply that their future and timetable for their lives is inextricably linked to God's timetable for Earth. Would that make any sense? That the lives of these other intelligent beings in other worlds would be created by God but have their lives tied to the failures and sin of the people that God created for Earth?
Would it make sense for God to create intelligent beings on other planets but mankind ruler over them? Psalms 8:3-6: “Thy heavens, the work of the Thy fingers, the moon and the stars, which Thou has ordained…Thou dost make him [man] to rule over the works of Thy hands, Thou has put all things under his feet”.
You may be right, and you may be wrong. All I can say is, whatever the truth is, it doesn’t impact my faith at all. I’m not going to pronounce that I know the answer with certainty. If the Bible is silent on the subject it’s because God didn’t see it as something important to give us information on (just like He didn’t see fit to give us great detail on what Heaven would be like). It’s enough that I know Heaven is and know what salvation is and what Jesus did for me.
The Bible’s focus is man’s creation and the earth, neither another’s creations nor any other place. The Bible doesn’t talk about atoms or gravity waves either, so I assume your position is that they don’t exist either.
Just because a creation exists and is sinful doesn’t lend credence to the notion that another creation existing is also going to sin.
I don't see how this follows. The Bible says nothing about the Western Hemisphere, and yet we can't infer that intelligent life doesn't exist here.
There are even huge amounts of things that Jesus said and did, that are not mentioned in the Bible. So many things, St. John says, that if they were all written, the earth could not hold all the books.
When God says ¨We¨ in Genesis, it´s been said by some rabbi that He was talking to the animals. Though I wonder that He wasn´t including the different inhabitants of the universe at that time...and if He has created since.
