There is a kind of original sin in Buddhism. It is called avidya (destitute of knowledge). Human beings come into the world under the dominion of avidya. It's like waking up in a virtual reality game but have no idea how you got there or how you might escape when the going gets tough. We are only a blank.
Now you are feeling hunger and fright and all those things that go along with being an infant. You begin your life being totally dependent on things outside of your control. You desperately cry for help like an abandoned kitten. You depend upon the love and care of those who brought you into this world — this not so kind world as you will one day find out.
Admittedly, life is always giving you hope but in the end you have to give up your carnal body. You have no idea where you're going to be after it passes away. Your imagination works overtime to create some kind of utopian world whether it's a heaven or a materialist utopia in which you will live forever in a temporal body.
Obviously, no great creator God is going to come down and help you (here your imagination is working overtime). You are on your own. But there, according to Buddhism, lies the escape route. It is where we transcend all appearances and conditions, even the perceiver and the perceiving which got us into this mess (avidya).
