the apostles were certain Christ rose from the dead.….and the world was flat and the sun travelled round the earth.
More precisely, of course, they told people that Christ had risen from the dead. Whether they actually believed it or had any evidence for it is as likely as Donald Trump's statements about injecting disinfectant.
Anyway, the answer to your question is that you haven't presented any such evidence or even a testable definition of god, and AFAIK neither has anyone else, ever.
He was not from this world. He said so
"There is no evidence for that statement. Indeed in Mark 8:31 and elsewhere he clearly stated that he was the Son of Man. So you either accept the word of Jesus Christ, or the bullshit put about by those who have cobbled together a spurious religion around his name. I always prefer the former, which, like most of what he said, is consistent with everyday observation and common sense."
What did he mean?
He didn't claim to be God, but he did state that he was the son of man. ?
Accept the word of Christ? Or the B.S.? I pointed out that you can't distinguish. You pick and choose what fits your beliefs. He said He was God almighty, too. In the same documents you cite in which He called Himself the Son of Man, He said He was GOD.
