No, it is evidence from several documents that it happened and that the pool of witnesses still exist. There are corroborative details in the documents. If you do not accept the evidence preferring another narrative that is up to you but then we are entitled to ask you for such evidence.
Complete non-sense - the claims in the gospels/epistles are about as weak as they come in terms on any credible evidence that the claims are true. So we can ask (and answer) the following questions in relation to the 'evidence'.
1. Is the claim fundamentally plausible. NO - your understanding of physiology tells us that people who are actually dead for three days cannot come alive.
2. Do the claims come from people who were actually eye witnesses (noting that even if they did people regularly mis-remember or misinterpret things they witness. NO - there is no evidence that any of the people making the claims were actually there and plenty of evidence to indicate that they weren't.
3. Was the claim made at the time of the event, or very close thereafter. NO - all the claims are in documents who earliest date is decades after the claimed event.
4. Do we know the relationship/links between those making the claim and those who might have actually been eye witnesses. NO - actually in the case of the gospels were aren't even clear who the authors are.
5. Is there any non-partial corroborative evidence, e.g. from authorities around at the time. NO - the nearest is from decades/centuries later, merely indicating what christians believed not actually corroborating the claim.
6. Are we sure that the claim as read is the same as the original claim by the author of the gospel/epistle - NO - our earliest actual versions are typically from centuries after they were claimed to have been written and we know beyond any doubt that there were almost countless changes in preceding versions from about 150AD-350AD. We can presume that similar changes occurred from 50-80AD to 150AD. So we cannot be certain that the claims actually existed in the earliest versions.
7. Are there multiple, independent sources for the claim - NO - effectively all the claims link back to the same place. That they may have appeared in different gospels is pretty well irrelevant if they based themselves on the same source mythology.
I could go on, but I can't be bothered.
