 Much of our research has to be subjective. And again, I want to thank you for all your investment in this. So my question, Michael, which is generic and vague, is there a plausible reason, even though these mysteries occurred thousands of years ago, why this was lost from generation to generation to generation? Why there is no real concrete reason other than our subjective reasons? And again, it's a generic and vague question, Michael, but I wanted to get your opinion.
