All preexisting bodies are dust. That doesn’t exclude the dust being another form before it was made into us.
“Jesus showed us that God is able to make something from nothing (a healthy eye “created” from spittle and dirt”
Dirt and spittle aren’t nothing and that’s kinda the point. The fact that a healthy eye was made from pre-existing material doesn’t mean that this wasn’t a miracle, that this wasn’t from devine origin.
The fact that I don’t read the Bible the way you do, doesn’t mean I don’t
believe it. I think it has the be approached with respect for the sacred authors and the ideas they were trying to illustrate.
Not mine and not yours. Our bodies began to develop when the sperm hit the egg. But Adam came directly from the dust of the earth. He didn't come from a beast. God created man with a dignity above the beasts.
The fact that Christ could create a healthy eye from unhealthy or could turn leprous skin into smooth (as did God a couple of times in the OT) or translate Lazarus from dead to living shows that He can create instantaneously and not over a period of years. We need to take God at His word in the creation account and not read our own preferences into it.
