This claim concerns Farage’s private belief state at age 18, which is not directly observable from public records. The only direct public source I found is Farage’s own 2011 interview in High Profiles, where he says he was “pretty much a non-believer” by 18; later profile reporting also describes him as not really Christian / not devout, but none of that is independent contemporaneous evidence of what he actually believed at 18. So the statement may be consistent with his own self-report, but it cannot be independently verified or falsified from public evidence.
