There's no green land
Just wasteland
When God send his blacksmith
To break the earth
Or rather to give rebirth
Now I'm running towards my vision
I was lead in the right direction
Waiting
For a Postdiluvian life in sin
Life will go on as everytime
Before
No matter what will happen
We will prevail
And evolution will save us from
Revenge of nature
There is a green land
My dreamland
In absence of rainbows in the sky
I'm sure you wonder why
Now I'm running towards my vision
I was lead in the right direction
Waiting
For a Postdiluvian life in sin
Life will go on as everytime
Before
No matter what will happen
We will prevail
And evolution will save us from
