Did Eve have any children before she and Adam ate the fruit of the tree of the knowledge of good and evil?

Or did they only begin to have children after they fell, and were put out of the garden?

When Adam called his wife's name:

Genesis 3:20 And Adam called his wife’s name Eve; because she was the mother of all living.

That was 3 to 4 lines before the LORD drove them out of the garden.

Why at that time would Adam call her the mother of all living?

Was he speaking prophetically of the their eventual children, and then the descendants of those children?

Or was he referring to children that she may have already bore to Adam in the garden?

Or was he speaking of both of these two things?

In Genesis 4 it speaks of Eve, that she bare Cain, Abel, and later Seth.

Clearly those are not her only children, she was to have many (multiply - many times, and also many at the same time?):

Genesis 3:16a Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children;

Genesis 5:4 And the days of Adam after he had begotten Seth were eight hundred years: and he begat sons and daughters:

And clearly some of those daughters were alive when Cain took his wife, either from among his sisters, or even nieces born to some of his brothers and sisters:

Genesis 4:1a And Cain knew his wife; and she conceived, and bare Enoch:

But, if Adam and Eve didn't have any children before they fell, then did they not keep what the LORD said?

Genesis 1:27 So God created man in his own image, in the image of God created he him; male and female created he them.

  28a And God blessed them, and God said unto them, Be fruitful, and multiply,

Did Adam and Eve only multiply, after they sinned, and were fallen creatures?

Did they not do what the LORD said, while they lived in the garden?

A possible argument for that could be made that maybe they were only in the garden for a short while, not enough time for Eve to get pregnant?

But then, the LORD's original creation and command was never kept, nor fulfilled, but only after they were fallen creatures.

Since the fall of Adam and Eve, all children have been born of a fallen father and mother, and born with a sin nature (except for the virgin born incarnation of the Son of God).

Even in the thousand year kingdom, those not already resurrected, will still be having children, still born with a sin nature.

The resurrected will not be, but will be as the angels of God in heaven.

But in the new earth, after the great white throne judgment, will there be any "not-yet-resurrected" people still alive, that were not cast into the lake of fire?

Or will only resurrected people inhabit the new earth?

Will there be no more descendants of Israel born at that time, and only a fixed number of Israel to live in the new Jerusalem, without change?

If so, then definitely, the LORD's original command to Adam and Eve, was never fulfilled as given, but only was carried out by fallen men and women?

And will that mean that it also never will be fulfilled as originally given?

i.e. was there never a child born to someone without a sin nature, and will ther never be a child born to someone without a sin nature, ever?
