How do you live in this world - filled with wars and chaos - with no hope of redemption or things getting better, and just thing “yep, this is all there is, life is good”. As Christians, we have assurance, certainty and comfort in that Jesus is coming back to judge the world, destroy all the wicked and bring us to eternal life. Atheists don’t have that. Even worse, some even prefer to insult this God. What’s keeping me grounded in this life is the knowledge that God dictates when my life ends- not me.
So now we’re changing the subject from the geographical fallacy to general existence of God-
The thing is, you made a truth claim - “The chance that the universe was created - just for us - is zero.” So generally, you’ll need to provide some form of way to show how you’ve measured that. Anyway, I’ll point towards the fine-tuning argument for that one. That if any property of the universe was different, it’ll collapse in on itself. We know the universe had a beginning - the “big bang”. There’s also the Kalam cosmological argument - science shows that the universe is finite and had a finite beginning, yet infinity exists. Infinite possibilities, or something more practical like the numbers of irrational numbers such as pi or the Mandelbrot set - how can infinity exist in a finite universe? Therefore infinity does and must exist. Such things can only exist if there is an infinite reality outside of the universe, such as the mind of God.
