Craig, who is just 15 years old, also praised the crowd's influence on his breaking of the world record by a full three seconds.
"I genuinely didn't think this would happen," Craig said. "It means more than anything in the world, I don't think anything will ever top this.
"I didn't realise that I'd broken the world record. [However] because of this great crowd I managed to. I wish I could do it all over again."
Craig's gold was ParalympicsGB's 28th of the Games so far.
