At its base, Christianity sinks or swims on the validity of the Story of Adam and Eve, and Original Sin. Even the most pro-science branch of Christianity, Catholicism, dogmatically states that there was a literal single pair who founded humanity, Adam and Eve, and who gave all of us Original Sin. This 4-min teaching video, aimed at the layperson, clarifies the reality surrounding evolution and the beginning of the human species.
There was no first human.
More details supporting humans originating from a group, not a pair. *
Here is THE challenge for any Christian: Find the place in evolution
where there was one couple who were so different than their parents that
they deserve the label "first humans."
Second, demonstrate that this "first human" couple was so much
different than their parents that they committed the "first sin." If
you cannot do this, why do you believe there was an Adam and Eve who
committed such an evil act that required god to send himself as a
sacrifice to "save" humanity? Oh, the story is a metaphor? If so, was
the Jesus story also a metaphor?
If one still accepts the story of Original Sin in any way after thoughtfully considering the above, then please address the illogical aspects of the story, and the scientific fact that there was no period in humans' background where there was no death and perfect happiness. Humans never "fell" from such as state. No "Original Sin", no need for a "Savior."
