Why can a monk sit down and give a scientific answer to a relic after his death?

Science cannot explain it. Although some scientists have inferred some conditions for the formation of relics, they can never be transformed into relics in ordinary people who meet the conditions. Only Buddhist monks are unique, and other religions cannot copy and forge them. If you have to give an explanation, you can find out by searching for the experiment "Water Know". Similarly, under the crystallization of abstinence, it is sarira.
