I'm about to refer to the original sin even though I have 

shallow knowledge.

First, do you know what is sin??

Sin is to commit fault to a person whether it was

unintentional or somebody committed a fault

deliberately regardless of the weight of sin.

Ordinary people usually call it a sin if someone has 

committed an error.

After all, we can see that sin was limited only for

inter-human, not everything in the world like an

animal or a plant or another thing.

Hence, we can know that human had been artificially 

making sin through the law which was made to protect

themselves.

Because whoever called human has been getting

weaker, if a human lives alone, not among others.

Every human had been instinctively knowing that they can't

live alone because all of them are very weak than the other

things in the world.

On the contrary, every human had been also knowing that

humans have the exorbitant power that barely countable,

because all of human has a logical resoning.

Then, what do you think is the meaning of the original sin??
I can state to you what is the original sin is, humans are

to seal their weak points through the God almighty.

As you know, Humans like to deceive someone and

vice versa.

It is because they don't like to show their inferiorities

than killing themselves.

Humans are very generous to themselves but, humans

aren't very generous to any people except to their own 

selves.

That is, humans also are very selfish although they are kind

owing to good and bad minds that humans have been

possessing.

Thus, we can infer that humans had made an original sin

by the use of God's existence.

Since humans started to look for their immortal life.

The worst inferiority of humans is to have a fate that

they must die someday.

Humans have known that they absolutely can't live for a lifelong.

Instead, humans believed that they can continuously 

live after death to fill their worst inferiority through

God.

Humans made many kinds of salvation so that no one

can prove that worst situation and humans used God

to eliminate their own worst inferiority.

To sum up, humans artificially made an original

sin to eliminate their own worst inferiority through the God almighty, that humans can't prove that worst

situation.

It is because humans don't like to show their own

inferiority due to their own self-esteem and pride.

Therefore, humans have proved their own worst

inferiority.

Then if they die, they can live forever in God's world-

also known as heaven.

Even though humans had artificially made an original

sin, God have been existing to those who was gotten

the royal summons by God.
