Will we ever grow out of War?

I like to think that just like the Nephilim had lots if war and environmental problems on Nibiru, they found peace and united to fix their home..that one day Man might do the same on Earth. I think that's why heaven is depicted like it is if people are describing the house of Anu on Nibiru.. From the text Nibiru would have no war and people live in peace , the sky would stay the same..reddish glow and possibly misty looking from the volcano's.. The building would be amazing. People live so long there compared to here, its would be like they never die. Sounds like all the Hollywood versions of heaven to me. Only thing is its not a afterlife just a location, the planet Nibiru. We too I think have the power to create with science and technology, our own heaven here on Earth. lets hope its sooner rather than later.
