..people who were involved in these historical events later documented them for us. This is how we got the four Gospels and the Book of Acts and the Epistles. All of it happened in the first century.
We don't know who the synoptic gospel authors are
or of any involvement they may have had with Jesus.
and Paul (Acts 9) records he saw no bodily resurrected
Jesus...
voices in his head are not evidence of a resurrected Jesus.
Regurgitating your tired old 'faith as fact' argument
isn't helping you...and by your own admission you
dont even identify as a Christian.
But you do sound like those fringe evangelicals
that refute scholarly consensus that Bart Ehrman
talks about.
