Can you believe in certain things without being religious?

but my point is we have no idea how the brain if at all can create consciousness,

If you insist on "no idea" and "if at all" then you are ignoring what they knew even 20,000 years ago from empirical testing ( konking on head rather than on foot). Are you going to stay adamant that we know Nothing about it? You make it difficult to go forward if you brush aside everything we find out and start each morning from zero.
Are you suggesting that if you go in for an operation you may suggest they put your elbow in butter rather than use any new-fangled 'make me unconscious' crap on you because, hey, we know nothing about how the brain makes consciousness - if at all. Would you stick to your claim of our state of knowledge?
