There is no such thing as totally innocent newborn baby, because every person that has ever existed and will ever exist descended from Adam?

Apart from the odd strange creature like Sea Horses and a few insects, male can't descend from other males, they are born out of a female.  Religion is a MAN MADE Fake news story, Adam & Eve are fictional people, their stories are used as a form of Brain washing.

All babies are innocent.

Only to people like you.  Rational people know that is just a myth.

Wrong.  Ezekiel 18 proves that statement is wrong.  Romans 9:11.

This is how you know the story of Adam and Eve is an explanation of our human nature and that this nature is not always in our best interest. A newborn would be totally innocent since it is incapable of acting on its human nature yet, but you can positively say that newborn will eventually do something that is not in its best interest or the interest of others. Human nature is the only thing that can be inherited in regards to the Adam and Eve story. It was already in Adam and Eve's nature to defy orders, where the story is just demonstrating that is why humans suffer, because they don't listen and believe they know better. This is true regardless of whether any Gods exist or not.

I disagree. Guilt is not inherited; what we inherit is sin--that is, imperfection. We have an innate, inherited tendency to screw up, because it's the way our minds work. 
 
Innocence is the absence of guilt, not the absence of sin. Newborns are innocent. As we grow and learn, we learn to screw up, but until we do, we are innocent.

Innocence vs sinless .. u confuse these words.
Yes, babies are innocent .. dun know evil BUT they are not .. sinless since they come fm sinful dna.

Genesis 8:21 says: "... So YAHWEH said in his heart: “Never again will I curse the ground on man’s account, for the inclination of the heart of man is bad from his youth up; and never again will I strike down every living thing as I have done."

Adam and Eve really existed. 

True statement, especially since I wrote it and it is what the Bible teaches.

Wrong.  The only linear bloodline that can be proven is Eve's.  Thus the female genealogy.
Peace.
