I brought this question up in another thread recently. What really confuses me is that when God created Adam he was created to be the only one of his species. There was clearly no intention of creating a woman. Genesis says: "It is not good that the man should be alone. I shall make a helper suitable for him" *emphasis mine.
That is not accurate. Before Gen. 2:18 came Gen. 1:26, "Let us make man (humanity) in our image... male and female He created them." Any failure to reconcile the two seemingly disparate verses leads to an error in understanding. With all do respect, you haven't reconciled the two. God's appraisal that all is good doesn't occur until the end of the sixth day... when both A&E had been created.
Before any effort is expended to try and find the flaws and errors in the story, try first to correctly understand what's stated.
Finally, if God created Adam and Eve perfectly, how was it that the very first two flawlessly perfect flagship models of His creation were able to muck everything up so much?
The Bible answers that question. Should I construe the question as an indication the Bible hasn't been read, or that it's been read but the connections to that inquiry weren't recognized when read?
First off, let's use our language intentionally. The Bible doesn't say A or E were perfect. Neither does it say they weren't flawed. What it does say is they were good by way of inference from Gen. 1:31. Then, via Rom. 5:12-19, we can infer they and they world in which they lived was sinless (because it was through Adam's disobedience that sin entered the world). This is where we arrive at the position that A&E were good and sinless (not perfect).
We know that A&E were mortal because the word "immortal" means "unable to die," or "not subject to death." So, in creating A&E God made (physical) death part of their constitution. What purpose might their death serve?
I make note of this seeming tangent to point out that we must think of the Genesis account 1) in light of the whole Bible, not just the first two or three chapters separated from the whole, and 2) it is an atypical story full of ideas that seem undesirable to already-fallen humans. If you're going to try the problem of Adam's seeming flawedness you're going to have to have a thorough knowledge of the whole and think in a manner consistent with that correct understanding of the whole.
The questions show a lack of knowledge and understanding.
Adam (and Eve) was good and sinless, but he wasn't complete. He still had to live and die and then proceed to the next stage or phase of his creation. If we have to use the language of "perfect," then the best we can say is that he was perfectly incomplete. In other words, thing of assembling an engine as an analogy: If you come to my shop and see a short block on the lift it isn't complete, but if I have assembled the piston rods, pistons, rings, etc. correctly there is nothing
imperfect in the portion of the engine hanging from the left. It is good and "sinless" but not yet complete. Adam in the Garden is good, and sinless, but incomplete. He is not flawed.
So change the question to more accurately reflect the text; otherwise you'll inextricably end up at a fallacious conclusion.
