Something I don't understand about the bible

Genesis 2 16-17
16 And the Lord God commanded the man, saying, “You may surely eat of every tree of the garden, 17 but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat[d] of it you shall surely die.”

God told Adam that the day he eats from that tree, he will surely die. But Adam did not die the day he ate the tree. He was just banned from Eden and was forced to live a harder life. He may have lost his immortality, but he didn't die for a long time later. So if God told Adam he would die the day he ate the apple, but than Adam didn't die. Wouldn't that mean God told Adam a lie?

Also, if God knows all and sees all, as people who believe the bible is God's complete word believe, didn't he know the serpent would successfully trick Eve and Adam into eating the apple? If he really didn't want them to eat from it, why didn't he simply block entry to it? Why did he allow a cunning creature that he knew would successfully tempt them into eating the tree, even after he told them not too.
Almost seems like it was God's plan all along to have them eat from the tree.

In Genesis Adam is a real jerk to Eve. They eat the apple, God comes down to Eden all angry, says who ate the apple? Adam immediately rats out Eve, "She did! OK I did too, but it's all her fault. You used her wiles to beguile me."

Adam and Eve both get kicked out of Garden of Eden, and God locks the door behind them. Eden is forever guarded by an Angel with a flaming sword. Because of their sin all women have to give birth in blood and pain. Genesis 3:16: " I will make your pains in child birthing very severe, with painful labor will you give birth to children." That seems very unfair to me. The God of the Old Testament was really mean.
