I had a scientific-based one I made a few years ago. Basically,
not so much worshipping but being thankful to the Primal Star
(the one before our Sun) that went Supernova, along with the
Giant Molecular Gas Cloud that it ran into, along with Gravity.
Those three things together, well, made up all of the elements
that literally make US, the Sun, Earth and all that, possible.
Forget the Big Bang - too far away.
We'd sing songs every week based on the latest scientific
research and the hymns would be entirely upgradable depending on
'what's new'... and each week would be centered around being
grateful for various scientific concepts that make us here and
possible.
Nothing supernatural required, just a whole lot of very specific
"Thanks!"
I still think it's a good idea, but I doubt I'll ever pursue it
