It is sin in general, and not merely one particular instance of sin,
that makes redemption necessary. If you can find any sin in the
world, then the claim is baseless. Proof of this is given by the fact
that many Christians feel the need for redemption but do not believe in
a literal Fall.
This claim implies that sin and redemption are about things that
happened thousands of years ago, not about anything happening to us
today. It makes religion less relevant to people's lives.
Origins are not determined by our personal decisions of what religion
to follow.
