Well, the arguments for theism are as put, reasonable. Everyone kind of thinks differently when matters conflict with their pure personal feelings on the matter at hand. I'd like to say that there are lots of sound debates for God but some just reject without even giving it a chance. Reasons such as there'd be a lot more skeletons around if there indeed was no God, as a lot more sodium chloride in the sea, and even how God possibly could have used evolution to create the earth since it was a long process of a few years. Also there is no evidence that God doesn't exist.
Not sure if you guys watched the video or not, but people were dumbfounded and you might even say blindsided when the people told them proof for a God. It's just an example of how no matter how much you think he doesn't exist, you could be very wrong.
