What does God need with an ark? And why would He send Noah to hell?

Haven't you seen Evan All Mighty? It was so he could stop builders from building in a valley.

EDIT: So if you just had to be a good person before Jesus in order to go to heaven, and now you have to be a Christian, then wasn't it better before?

Your questions are valid but your answer is only partially correct

There is nobody before Jesus... In other words,, Jesus existed before

he was born. The example of this is.. :

[John 1 : 29 ~ 30]

29. The next day John saw Jesus coming toward him and said, "Look, the Lamb of God, who takes away the sin of the world!

30. This is the one I meant when I said, 'A man who comes after me has surpassed me because he was before me.'

John clearly states that Jesus exixsted before him.. and scientically

it is very strange and unagle to explain.

You can not dissect the bible with modern scientific understanding

Bible says God is in Jesus and Jesus is in God so they are same

But how can two being be one ?

That's Bible for you.. it does not always make sense.. not because

it is false.. but because we lack the inability to fully understand.

You can not expect an ant to fully understand quantum physics..

But that does not mean quantum physics is false...

So.... The answer is ..

1. Noah did not go to hell

2. People before Jesus was born did not go to hell

(if they believed in Yahweh(name of god) in Bible)

well... reading the bible u see that those who were faithful to God, but died before Jesus went to Abraham's bosom, which was like a place for them to go since no one could go to heaven until Jesus paid the price... so Noah didn't go to hell.....

Those "good" people went to paradise. During the three days in between Jesus' death and resurrection, he went to paradise and emptied it (sent them to heaven).
