And a majority of us on here do not because there is an absence of evidence. The Bible is the claim, not the proof.
Atheism is not a belief. It is the disbelief or lack of belief in the existence of God or gods as the official definition describes.
I don’t care what he was. Like other Atheists, I concluded that the biblical Jesus doesn’t exist. I also concluded that he was made up by the Romans to push a political agenda for Emperor Constantine in 325 A.D.
It still doesn’t evidence the Biblical Jesus that you believe in exists.
What objective evidence can you demonstrate for any deity?
