I'm not a historian, so I didn't go by Carrier's reasoning.
When I was introduced to Christianity (maybe around age 11), I tentatively accepted the resurrection. But I understood that I would need to check it out.
Around age 16 or 17, I went over that again. The gospel report (in Matthew) was just too fantastical. If it really happened as described, then reports about this would have quickly spread around the world. Yes, this was an era before modern journalism and before the printing press. But for events that fantastical, it would have spread by word of mouth.
But it did not spread as it should have. Therefore the gospel report is very doubtful.
