Both Adam and Eve came into the world without sin, so that is not an "attribute that belongs only to Jesus". And Mary's sinlessness comes always and only through the grace purchased by the death of her Son.
She was no taken into heaven without dying.
Strictly speaking, the Church doesn't insist on the "without dying" part.
She does not hear and answer our prayers.
How do you know what the saints in heaven do and don't hear and answer? Have you been there?
Likewise, I'm sure. The Catholic church can't say for sure either.
They why do Catholics pray to them? They must believe that they can hear us. Where is that found in Scripture?
Adam and Eve didn’t *come into the world*. They were created by God and put there. It’s not the same as birth.
You've stated this example several times now as some sort of "proof text" that Mary was sinless. I don't see it that way. Adam and Eve were the first humans created but "sin" had already come into existence way before them when Lucifer led a third of the angels in rebellion against God. That the humans had not "sinned yet" is not to say they were "sinless". They certainly had the same capacity to sin and Satan sure didn't have to wait long after God gave them his first law - to not eat of the tree of the knowledge of good and evil - to deceive them into the first sin. All humans born after that - with the exception of Jesus - were born with a sin nature and were and are - by nature - sinners and at enmity with God from the womb. Mary, as a human, was under that same curse and that is why SHE needed, and confessed to her need of, a savior.
This doesn't in any way dishonor Mary. It acknowledges her humanity and ratifies the human nature Jesus himself has - yet without sin - because of his divine nature which was why he could be a sacrifice for all sins.
