In both cases, there was available all the evidence a skeptic could want. Peter even proposed and conducted a scientific test to collect further evidence. Unfortunately, his hypothesis failed to account for a hidden variable: Faith.
Jesus' original disciples may have found Him to be too incredible to believe in. His disciples today may find Him too believable to be incredible. If I have always known by faith that Jesus rose from the dead, then what would I find remarkable about Jesus rising from the dead? That would be like finding it remarkable that clouds float in the sky.
And if I don't find Jesus' resurrection remarkable, then I won't remark on it. If I don't find Easter remarkable, then (if you'll pardon the rhetorical over-reach) Easter will leave no mark on me.
