Nah, but the 2020 divided by 666 equals 30330 is legit.
The Mohammed theory is interesting but not correct I don’t believe. The Beast or Antichrist is alive when people take the mark. Mohammed is dead as far as I know. The AC could claim some kind of ancestry to Mohammed. In ancient Hebrew and Greek the letters of their alphabets corresponded to numbers. Names back then literally had a number. If you read the works of Tim Cohen, the only notable person whose name added up to 666 in Hebrew (also English) is Prince Charles.
