Because all people would ultimately have done the same thing as Adam and Eve,
God has two choices:
1. Don't make people, and avoid giving them the opportunity to select the good or the bad;
2. Make people, and give them the opportunity to select salvation or not.
There's no such thing as two choices when your omnipotent. There are only infinite choices.
Unless of course your god (the Jesus thingymajig one) isn't omnipotent, which renders it another one of these silly false ones.
Why do you keep contradicting yourself. Now you suggest that the Almighty is omnipotent, and yet He can't make it so that He has only two choices.
If he can make it that he has only two choices and he can't have more than two choices, so then he's not omnipotent because he doesn't have more than two choices. Omnipotence brings paradoxes.
Also, your god creates people so that they have two options after death? Losing their free will forever and spending eternity praising him, or burning in hell for eternity? All I know is that the flying spaghetti monster has way more balls than your god. Why not just show himself?
What part of "God" didn't you see? God has the ability to be almighty in two choice or any choices or no choices.
God created people to be similar enough to Himself that they had many options. Then people threw it all away by choosing the devil over God. Then God sent His Son, Jesus, to open up the choices for people again. Now God Himself gives people the results of their choices by manipulating the universe according to the faith in Him that they have. And more than that, He further activates their faith for them in the direction they want their faith to go.
Regarding Heaven or Hell... God made people to last indefinitely when He made this universe, maybe even to never die. Then people threw it all away. God still wants people to live indefinitely, but the operation of the universe changed when the people threw away there God likeness. So, God is making a New Universe for people where things will be different in such a way that people will never throw their God likeness away again.
God is holding the choice open for people, as long as they live this life. Either choose God and the New Universe, or choose to remain here when this universe is dissolved so God gets His energy back from it, that He put into it.
Be glad that God doesn't show Himself in person to you. You would have far better chance at remaining alive in a Fukushima meltdown - or in the hottest part of the sun - than you would in the presence of God... at least in the imperfect form in which you are existing right now.
