I’ve read/heard conflicting opinions on this from friends and sources I’ve found online, so I was hoping to find a concrete answer here. Just to be clear, I’m not asking whether Jesus actually created miracles or was resurrected.
There's always more that can be said, but you might like this quite extensive section of our FAQ on the matter. The historical consensus is that yes Jesus was a real person who existed. The miracles we leave to the theologians to discuss.
