Neither was I there nor where you there, hence we both should consider all the evidence, and not just take fantastical non-repeatable claims at their word.
Your claims sound similar albeit from a non-trinitarian perspective to Peter J Williams who debates Bart Ehrman here:
You may be interested in the Williams vs Ehrman debate because Ehrman does not even have a go on miracles which I think he potentially could have had he wanted to.
For a shorter look at the problem with contemporary claims of miracles you might watch this video examining and deconstructing a modern miracle and think about why we can't just take stories of miracles at their word if you forward to 3:25;
Its not about taking sides, you are trying to say something is true or not true based on it's source. Jesus had authority over a small number of men, He only had something like 11 fulltime disciples prior to the alleged resurrection, He was hardly a scriptural authority.
If that is the case there is nothing that God did which is not repeatable if it is just obeying the laws of nature. Which means that man can potentially do anything God can do. So man could potentially create life? Then why aren't there JW scientists studying how life was formed?
In my opinion.
