Women saw the angel and empty tomb first, according to all four gospels.
All four gospels - you mean those documents purported to have been written decades after the event and where the early actual copies of the claim we have is likely from 150-200 years after the event. So a claim in a gospel (or even all four) is the flimsiest of evidence that what was claimed to have happened actually happened.
Add in that there is no credible evidence whatsoever that angels actually exist, so without the a priori evidence for the existence of angels any specific claim of angels is moot.
So what we are left with, even if we soften our criteria for credible eye witness evidence (which doesn't involve hearsay from hundreds of years later with no independent corroborative evidence) we are left with some people finding an empty tomb. There are all sorts of credible explanations for this, as I've stated early. The least credible is that a dead person suddenly came alive again.
