If Adam and Eve had never ate from the forbidden tree how long would they have lived?

Forever. Just imagine when they started to be fruitful and multiply. Will there be enough room in the garden and on earth for people to fit in. Note God made only one earth. Thus God intended for adam and eve to eat of the fruit and that lucifer now the devil to be a murderer from the beginning. How mean is that?

Unknown, but obviously they would have died eventually since they were biological creatures, and no biological creature can live on Earth forever. And if they did, the Earth would soon be covered by people, every square yard.

They would have live forever. They did not have to die. The only reason they died is because they disobey God. And that is why we do not live in a paradise today, and why we die because we are Adam’s children.

Adam and Eve punished for their disobedience, their lack of appreciation? According to some religious teachers, at death Adam and Eve went to heaven. But is that reasonable? Does the Bible say they went to heaven? Why, if that were the case, Adam and Eve would have been given a greater reward and blessing for sinning than they would have had for being obedient.

Had they not sinned, the best they could have hoped for was to live in an earthly Paradise to time indefinite, for God said nothing about an existence for them elsewhere. No, it is not reasonable to conclude that Adam and Eve improved matters for themselves by disobeying God.

When they were created, Adam and Eve had no enemies whatsoever. They were perfect humans who lived in a paradise.

They enjoyed a close relationship with their Creator as his son and daughter.

Their life prospects were indicated in the very commission God gave them. Genesis 1:28.

To fill the earth and subdue it could be accomplished in a certain amount of time. But to continue to have in subjection every living creature that is moving on the earth, Adam and Eve would need to live forever, Adam never having to abdicate his oversight by dying.

God said to Adam: As for the tree of the knowledge of good and bad you must not eat from it, for in the day you eat from it you will positively die. Genesis 2:17.

Thus, death would come upon them only if they disobeyed God’s command.

Otherwise, they had the prospect of living on indefinitely in that earthly Paradise called Eden. Clearly, humans were made to live, not to die.

Forever.

Indefinitely.  Sin is death. It is spelled out numerous times. That's why when people ask if it's harsh punishment to go to hell, it's not.  God created us, and He said that sin is death, and we choose to do it anyway, and further, some don't repent for it knowing that this is the outcome.  Arrogance, pride and willfulness caused death.  

They would have live forever. The only time death was mentioned was is they ate the forbidden fruit. So if this they hadn’t ate the forbidden they would have lived forever. That act of disobedience did not change God’s purpose.

Jesus Christ confirmed that:

New World Translation

Matthew 5:5 Happy are the mild-tempered, since they will inherit the earth.

They would have lived forever.

Forever. They were not destined to EVER die. That was not the original plan. [So the story goes]
