I think you don't appreciate the complexity of even the simplest multicellular organism and their training environment. Nothing to be ashamed of because no one understands that complelxity. The entire scientific and engineering domains only understand a fraction of it. If you want to talk about hubris, you should consider your own. To insist this sliver of computation is all that's needed for life to be conscious reeks of it.

Lack of explanation is not proof of existence.
