I Bow to the authority of the Bible Alone and not evolution theory.

I bow to the authority of Scriptures alone  that Adam and Eve were actual Historical Person created by God :
Paul the apostle takes Adam as actual historical person [ Rom 5: 12-21, 1 Cor 15: 20-23].
 Paul is drawing a parallel between the one man Adam and the one man Jesus Christ. Also Christ is refereed to as last Adam [ 1 Cor 15: 45].
Therefore I am not ready to listen to other voices. Man is a creature of God and accountable to Him.

Federal Headship by John Calvin Rom 5;12-19.

This is also called representative headship.
[a] Just as Christ is the representative of all believers, Adam is representative of all humanity.

[b] As our representative Adam can sign  agreements on  on behalf of all humanity and the agreements will be binding just as an MP, President or King who sign any agreement on the behalf of the people.

[c] Similarly when Adam broke God's covenant we all broke it hence we are all sinners.
