Hebrews 4: 15 For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who has been tempted in every way, just as we are--yet was without sin.
Hebrews just reiterates what we already know from the Gospel.
You basically implied that the only temptation Jesus had was the temptation by Satan on the mountain , even if that were true it would still count a HUMAN temptations because he had a HUMAN nature.. just as we all have. Again He got his Human nature from Mary. being human is more than just having a body..our dogs have bodies but they are not human. Would we call a child that was born with no arms or legs fully human ...of course , not based on his body, but on the nature he has within him .
If Mary was only to pass on a body, without the Human nature then she provides only a gene pool and nothing else. A sinless Mary would not have a human nature, but a divine one. Hebrews makes clear that Jesus was tempted just as we are, as he lived a life like ours..
***A sinless Mary would not have a human nature, but a divine one.***
Using your analogy, Adam and Eve had a divine nature before the fall.
