3 yes the resurrection has explanatory power. It exolains why early Christians where claiming that jesus rose from the dead.
No it doesn't, magic is not an explanation, it is presenting a mystery as a solution to an unevidenced anecdotal claim. It also has Occam spinning in his grave.
4 explanatory scope refers to the number of things that the hypothesis explains , (1) the resurrection explains the empty tomb , (2) the belief in the resurrection, (3) the sudden convertion of Paul, (4) the rise of early christianity etc. (No other naturalistic alternative explains athus much)
It doesn't explain anything.
1. You have not presented any objective evidence there was an empty tomb, but claiming it could only be emptied by inexplicable magic is not an explanation of anything.
2, 3 and 4. Seriously? The belief explains the belief, priceless.
(No other naturalistic alternative explains athus much)
Firstly that is another argumentum ad ignorantiam fallacy, please look that up, and try and understand that it is irrational to imply a belief or claim gains credence because we don't have an alternative claim or evidence.
Secondly any natural explanation is by definition more probable, and for pretty obvious reasons I'd have thought. However here is a list:
1. The body was removed for reasons unknown.
2. The body was deliberately removed to give credence to a supernatural claim.
3. There was no tomb, and the story is fabricated, either partially or wholly.
4. The tomb was never empty, and someone made the story up, and named false eye witnesses decades after the fact.
5. The body was removed for nefarious purposes, by persons unknown.
Note that off the top of my head, all of those don't require any unexplained magic, like resurrections, and ipso fact they are more probable than unevidenced claims for a resurrection, since we know they are all at least possible.
NB please note possible, and probable are not the same.
