But, of course, that didn't come from nothing.
My point is if you pull up history on the god of the bible, Yahweh has numerous links to previous polytheism. The history is debated still, but clearly the God of the Abrahamic faiths is made up.
Christianity as well hijacked numerous pagan rituals and changed itself to spread to more people
It's fairly unlikely that he didn't exist, though everything about him was written down several years after his death.
Someone named "Jesus Christ" most likely did not exist. The references we have to the individual have been linked to church forgeries and faked documents, with no hard evidence to his existence. Clearly a guy in the middle east walking around performing miracles did not exist.
Regarding the name "Jesus", we have numerous pieces of evidence that say the first name, all of which come decades after and came at a time when the Christ cults were growing in popularity.
The biggest difference between someone like Pythagoras vs someone like Jesus is we have some pretty hard substantial documentations on his life, who his parents most likely were, development of ideas, and even you know that whole Pythagorean theorem named after him.
With Christ we have conflicting records, no known date of birth, no known parents, no known criminal record, no mention of him in official Roman documents. We have had countless searches for evidence to prove he really existed, and all we find are anecdotes and references made decades to centuries later. The earliest record from the Romans comes in at around a century later from Josephus, the first century Roman scholar who mentions Jesus twice.
So now I have to put forward a question one should always be asking in these cases
What is more likely?
A man born of a virgin walked around the middle east for a few decades and did some miracles and no one said anything or wrote anything or even made a passing mention of him until decades to a century after he died?
or
Within those decades to the next century a couple generations of people died, others were sucked into the Christ cult movements, and much like today people exaggerated their claims and made up the character to suit their needs and spread the "gospels" as truth?
The Jesus myth is something I have spent a lot of time researching, I am wholly unconvinced this character existed in any meaningful way.
