"Running out of time" - you plan your presentation ahead so that you do not run out of time. There were handouts from the proposers.
"Didn't Craig and Copson know that they would be going first?"
Of course they did. The first speaker for the motion presented three philosophical arguments for God's existence and the first opposition speaker should have responded to all these points to give the second proposer the chance to respond. By leaving two of the three reasons to the last speaker meant that there was no chance to respond to his points. Each speaker should respond to the entirety of what the previous speaker said.
"Given the short time Arif had"
Arif Ahmed took the longest time for his speech.
"Delusion"
If you take delusion to mean simply a mistaken belief then you could reword the motion to be "this house believes that God exists" since the fact that belief in God exists is a given. As I said, Dawkins writes about more than just the question of God's existence. Remember the grammar of the proposition labels the belief rather than God as being a delusion. That belief must belong to human beings.
"total mental capacities"
The speakers confined themselves to talking about belief in God, not general mental abilities.
