There are hundreds, nay, thousands of people who have seen UFOs and artifacts and have risked personal ridicule and perhaps death upon reporting what they saw. If you want to know who the are and what they said, just search the Internet.
I'll not go into my personal relationship with Christ again because your search function for this forum still works. It is immaterial for the point I was making.
Jesus Christ is the single most attested historical actor in the ancient world, even though only a handful wrote about their experiences with Him (perhaps eight New Testament writers knew Jesus directly, and only two of the Gospel writers were of the Twelve). Of what was written, we know from it that many, many thousands saw Him before the Crucifixion, and as late as thirty years after his death, 450+ could still attest to personally having seen him after the Resurrection. And, of the many direct witnesses before and after the Crucifixion, at least 2,000 were killed for their testimony.
Had modern communication and literacy existed in the 1st century AD, as John wrote, there wouldn’t be enough books in the world to fill the pages of the eye-witness testimony.
You need to walk back your claim.
