No, Jesus did not state that Adam and Eve were created directly by God. You are reading far more into the text than is there. Jesus said only that the Creator God “made them” (Matt 19:4–6; Mark 10:6–9), which states nothing about how he did so. You are injecting the idea from outside the text that it was a direct, instant de novo creation—and then making that do all the work for you.
For the record, I agree with every statement Jesus has ever made. However, I might disagree with how you’ve interpreted one of his statements—especially if something outside the text is doing all the work. That is eisegesis and ought to be rejected.
I don’t know what you were going for here. Yes, Genesis 1:24 says, “God said, ‘Let the land produce living creatures according to their kinds: cattle, creeping things, and wild animals, each according to its kind.’ It was so.”
True—I think? I am not entirely sure what your question is asking. I mean, yes, he created Adam first divinely, but he followed that with creating Eve divinely, too. It’s not as if he created Adam divinely but Eve undivinely. But then what is “divinely” even supposed to mean? It is a little vague here in a conversation that usually involves terms like “immediate de novo creation” (as opposed to mediated creation through ordinary providence).
Unknown, due to insufficient biblical data. Whilst I know how the different creationist interpretations answer that question, I am not convinced by any of them, so it remains an open question. I prefer the interpretation suggested by Walton, but it likewise doesn’t provide a definitive answer to that question; in other words, his interpretation doesn’t exclude either view, whether they had parents or were created de novo as adults.
Currently, I personally lean toward them having parents, but that’s speculative and tentative and I could easily be moved with a solid argument.
