Nearly all the evidence we have from the first Century confirms it; that explains why we have given this slider an initial value of 90.
90 / 100
Background worldview
Some of the answers we have to the big questions in life (our "background worldview") are also relevant to how likely we think the resurrection is. In effect, the real question you should ask yourself is, "To what extent do I think that there is a God who could have raised Jesus from the dead?" We start with a rather sceptical initial value of 10 for this slider, but there are more reasons than you might think for increasing this.
