The fisherman Peter was many things, but he was not very smart. There is no way he could have led a conspiracy to invent a false Messiah and convince billions of people it was true.
Actually, I think it was Paul who did most of the convincing.
That's true, but Paul never met Jesus until AFTER he died.
There is no way Paul could have invented Jesus, his name was already well known, and he already had whole communities of believers, before Paul first made an appearance in Act of the Apostles.
If anyone INVENTED Jesus it would have to be Peter, James, and John, who are participants in most of the important stories in the Bible.
But to claim Jesus was an invention defies belief. It literally makes no sense to believe that.
And yet, that is what one of your fellow atheists said today, that Jesus never existed.
It's a claim as absurd as saying the Earth is flat.
