One men's trash is another men's treasure, one men's heaven is another men's hell. Heaven then, is very much based upon perspective and preference even if there is a heaven that meets some men's satisfaction.
One man may enjoy the light and beauty of God, while another man may enjoy the solitude and darkness of God. God exists in all places (omnipresent), God exists within complete darkness and the brightest of lights.
One man may find comfort in being embraced and surrounded by the light of the Creator and another man might find comfort in being penetrated and subdued by the deepest and darkest places of the Creator. There is no heaven that meets all men's desires, there is no single place that can be considered heaven for every man.
God knows this, just as there is countless souls there are countless places of experience for every type of soul.
Just as no one (in their right mind) would force every culture of people on Earth to one country or state, God does not force every soul to a single heaven. God loves variation and difference, God loves a myriad of shapes, colors and sizes. All God's creatures have a place in creation. It is the very contrast of difference that the Creator delights in, for God is what brought variance into existence to be celebrated and enjoyed.
Not all men wish to dwell in the very same place, what one soul likes another soul would never dream of and what one soul finds delight in another soul is repulsed by.
Cultures and societies of all kinds extend well beyond this one planet, extend well beyond into the afterlife. This is what makes creation beautiful and fun, this is what brings joy into a childlike heart and what every soul would delight in if they truly opened up their mind, intellect and curiosity trusting in a God that surpasses segregation and a tribal mentality.
If everyone soul here knew that, it might change their whole idea and perception of God giving them freedom of thought and something to be excited about and invest belief in. Spirituality though is not all about the self as it relates to the progression of the souls growth but heaven (being a souls desire) is the outcome of each souls maturity and is propelled by their own interests and passions.
