Evidence God Exists

[Thor]

I was just countering his claim by providing possible scenarios that could've occurred during that tragedy which do not contradict or deny the existence or God and the power of prayer.

Yeah, "possible scenarios" for which you have no evidence. How about this? After the planes crashed into the towers, invisible trolls supported the buildings which allowed many people to escape. Otherwise, the buildings would have collapsed immediately! The trolls held up the building as long as they could, until the flames became too much for them. At that point they had to let go and save themselves. But, if not for the trolls, many thousands more would have died that day! Praise be to the trolls!

And this scenario is just as likely as yours. Plus, I have just as much evidence as you do!
