Need an argument answered

[GTR-1]

I go to Halden high school and when we had religion for the very first time, the lecturer at the end of the class very subtly shared the gospel with all of us and this is not even a private school, it's a state school. I figured I need to challenge this guy so I anonymously sent him an e-mail asking him how he knows that the Bible is true and he said because of Ivan Panin's discovery of the heptadic structure. I never heard about this before but smells like BS nevertheless I need an answer
