Sapiology.
A religion where there is no organized service, but we all work together to become a united species. We acknowledge each other's individual perspectives and personalities, and we integrate them in our approach to the universe. Our main goal is to see the world become a place where people are free to live the lives they need and want to live, with the caveat that their aims do not directly obstruct the manner in which another chooses to live.
We also work on making sure that society is consistently working towards becoming more united and people cohabit the Earth in a more peaceful manner, so that future generations may work towards a better society.
Why? Because we recognize that without each other, humanity means nothing. Without other humans, there is no purpose - if there is no one to remember us, we have achieved nothing, we leave no mark on the Earth. Humans work so hard and spend so much time searching for a purpose and longing to leave their mark on the world - but it's not the world you need to leave a mark on. If tomorrow, the human race was wiped off the face of the Earth, we would have nothing to show for our existence. We might leave structures and technology behind but without other humans to utilize it, the Earth would reclaim them in a natural manner and they would serve no purpose. Without each other, we serve no purpose and we mean nothing - our aims should be to continue to provide a place where our species can thrive and become more united because without each other, we leave nothing when we die and the lives we lived have been for nothing, just time spent observing time passing and events that hold no universal consequence. In order to find a life fulfilled, we must fulfill each other.
