The premise from which my work has grown is that, if there was no death before sin, then evolution (the origin of species) is impossible.
Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned: (Romans 5:12)
This premise is however founded on the fundamental belief that God does not lie, His Word is true.
God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good? (Numbers 23:19)
In hope of eternal life, which God, that cannot lie, promised before the world began;. (2Titus 1:2)
Of his own will begat he us with the word of truth, that we should be a kind of firstfruits of his creatures. (James 1:18)
