Originally Sin?

The question here is; is Original Sin true or a false concept created by man?

I see post all the time about Adam’s sin and it’s supposed to be the reason why death is
in the world. Religious Christian zealots claim that because of the original sin of Adam eating from The Tree of Knowledge man was condemned to death, as it states in The Bible, Gen 2:17.

This is then used as the reason that Jesus (Yahshua) had to be born into this world and die on the cross as the savior for mankind to allow us to live eternally in the abode of Heaven. But one thing makes no since in this statement because, if man was meant to live forever in the flesh in the first place, why did Jesus have to die for us to only live in heaven eternally, not in the flesh as pastors and preachers claim. There is no mention in the beginning of the Bible about man living forever in heaven, nor does any pastor or preacher teach this concept, although the Tree of Life is mentioned in Genesis.

So once again, is this truth or a lie?

So the story goes, God created man, God is All Knowing, God told man to not eat from a specific tree that he created, man, who had been given choice, chose to eat of the tree anyway. Then God punished man for doing so by allowing man to die, but first let them live for up to 999 years. Then send his son to die on the cross 4000 years later so that man can live forever in eternity! This is the gist of the story, right.

Here is where the problems come in with this story!

1) If God is All Knowing then He had to Know that Adam would eat of the Tree of Knowledge, which meant that it was part of the Divine plan, and should not be considered sin

2) Man could never have been designated to never die because that would have meant that the world would have been overpopulated 1000’s of years ago with 3 and 4 thousand year old humans

3) Why would God send Jesus to die on the cross so that we can live forever in Heaven when the original sin caused our life in the flesh to be cut short, shouldn’t Jesus’ death have been so that we can live forever in the flesh as it was originally planned

I already know what the zealots are going to say about this; God works in mysterious ways, you can’t use mans logic and reasoning when it comes down to God’s plans, etc, but this is one of the first stories in the Bible and it cannot be true by any standard of sensible thought. The only standard it works under is, blind following the blind. And this is just the tip of the iceberg!
