- merely asserts that his "belief system" is not invented
Then prove me wrong Little Johnny?
All you have to do is trace Preterism to one man?
Show that one man invented Preterism, and that it didn't exist before the one man.
It's really easy to do that with Dispensationalism. Dispensationalism was invented by Darby in 1830, and didn't exist before Darby invented it.
Same thing with Mormonism. Mormonism was invented by Joseph Smith, and didn't exist before Smith invented it.
BTW, Smith and Darby were contemporaries, along with Charles Taze Russell, Ellen White, and Mary Baker Eddy.
The era was known as "the age of the cults".
