You claim that there is more. There is currently no evidence of "more".
So you have to provide evidence.
BTW: awesome move, to just unilaterally end the conversation, if you're actually challenged. Totally not ignorance, nope, that's a scientist right there.
Why is it conscious? This suggests that an explanation of consciousness will have to go beyond the usual methods of science.
First of all, "why" is simply not a valid scientific question. "How" is the only relevant term.
Secondly, this is a philosophy article. Philosophy is not a science, to explain a brain. We don't fully understand quantum physics, would you ask a philosopher about that?
And finally: insulting another person, because they question your belief. Awesome behavior. Do you want to assemble a mob next to burn me at the stake?
